The West Pier in Brighton, UK. This pier gradually collapsed during the early 2000s, and multiple fires in 2003 left little of the original structure.
The late morning sun creates patterns under a bridge annex over Melbourne's Yarra River at the entertainment precinct of Southbank.
The contrast of the light-and-shade between the precise ones from the wooden slats at the top and the more diffused from the molded metalic surfaces catches the eye.

There were many interesting exhibits; but they were impossible to photograph. As a result I'm sharing very few photos here.
There's been a lot of hoopla about the possible sale of the Packard facility. Best line from the article? "The majority of those old structures are believed to still be structurally sound."
Good luck, pal.

Originally built around 1880, the Henninger Farm Covered Bridge, also known as Stroup's Bridge, spans Wiconisco Creek in Washington Township, Dauphin County, Pennsylvania. The bridge is 72 feet long. Arson heavily damaged the bridge in 2000 but it was rebuilt in 2003.
Historically, Wiconisco Creek boasted six covered bridges, and Dauphin County had a total of nine. However, flooding caused by Hurricane Agnes' remnants in 1972 destroyed all but three of the county's covered bridges. Henninger Farm Covered Bridge holds the distinction of being the only one remaining in its original location. Since a modern concrete bridge handles most traffic today, the Henninger Farm Covered Bridge is restricted to pedestrian use. Notably, the bridge's historical significance earned it a spot on the National Register of Historic Places in 1978.

Gumiel de Izán (formerly Gumiel de Hizán[2]) is a municipality located in the province of Burgos, Castile and León, Spain. According to the 2004 census (INE), the municipality had a population of 665 inhabitants.
The nucleus has been a historic-artistic complex since April 26, 2004. Interesting examples of popular architecture can be seen in its streets, apart from wine presses: houses with the ground floor and structural elements made of stone, and the upper floors made of adobe with timber frame The facades were traditionally plastered, but in recent restorations the aforementioned elements have been left exposed.
A formation of Lockheed Martin F-35A "Lightning IIs", from the 388th Fighter Wing and 419th FW, refuel over the Utah Test and Training Range, Utah, as part of a combat power exercise Nov. 19, 2018. The exercise aims to confirm their ability to quickly employ a large force of jets against air and ground targets, and demonstrate the readiness and lethality of the F-35. As the first combat-ready F-35 units in the Air Force, the 388th and 419th FWs at Hill Air Force Base, Utah, are ready to deploy anywhere in the world at a moment's notice.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities.
Service officials had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational production aircraft due to high costs, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35. The last F-22 was delivered in 2012.
Development
Origins
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Su-27 "Flanker"- and MiG-29 "Fulcrum"-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing strong emphasis on stealth and supercruise. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986. Lockheed teamed with Boeing and General Dynamics while Northrop teamed with McDonnell Douglas, and the two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the YF-22 and the YF-23, respectively.
Dem/Val was focused on risk reduction and technology development plans over specific aircraft designs. Contractors made extensive use of analytical and empirical methods, including computational fluid dynamics, wind-tunnel testing, and radar cross-section calculations and pole testing; the Lockheed team would conduct nearly 18,000 hours of wind-tunnel testing. Avionics development was marked by extensive testing and prototyping and supported by ground and flying laboratories. During Dem/Val, the SPO used the results of performance and cost trade studies conducted by contractor teams to adjust ATF requirements and delete ones that were significant weight and cost drivers while having marginal value. The short takeoff and landing (STOL) requirement was relaxed in order to delete thrust-reversers, saving substantial weight. As avionics was a major cost driver, side-looking radars were deleted, and the dedicated infra-red search and track (IRST) system was downgraded from multi-color to single color and then deleted as well. However, space and cooling provisions were retained to allow for future addition of these components. The ejection seat requirement was downgraded from a fresh design to the existing McDonnell Douglas ACES II. Despite efforts by the contractor teams to rein in weight, the takeoff gross weight estimate was increased from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), resulting in engine thrust requirement increasing from 30,000 lbf (133 kN) to 35,000 lbf (156 kN) class.
Each team produced two prototype air vehicles for Dem/Val, one for each of the two engine options. The YF-22 had its maiden flight on 29 September 1990 and in flight tests achieved up to Mach 1.58 in supercruise. After the Dem/Val flight test of the prototypes, on 23 April 1991, Secretary of the USAF Donald Rice announced the Lockheed team as the winner of the ATF competition. The YF-23 design was considered stealthier and faster, while the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky. The aviation press speculated that the Lockheed team's design was also more adaptable to the U.S. Navy's Navalized Advanced Tactical Fighter (NATF), but by 1992, the Navy had abandoned NATF.
Production and procurement
As the program moved to full-scale development, or the Engineering & Manufacturing Development (EMD) stage, the production version had notable differences from the YF-22, despite having a broadly similar shape. The swept-back angle of the leading edge was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%. To improve pilot visibility, the canopy was moved forward 7 inches (18 cm), and the engine intakes moved rearward 14 inches (36 cm). The shapes of the wing and stabilator trailing edges were refined to improve aerodynamics, strength, and stealth characteristics. Increasing weight during development caused slight reductions in range and maneuver performance.
Prime contractor Lockheed Martin Aeronautics manufactured the majority of the airframe and performed final assembly at Dobbins Air Reserve Base in Marietta, Georgia; program partner Boeing Defense, Space & Security provided additional airframe components as well as avionics integration and training systems. The first F-22, an EMD aircraft with tail number 4001, was unveiled at Marietta, Georgia, on 9 April 1997, and first flew on 7 September 1997. Production, with the first lot awarded in September 2000, supported over 1,000 subcontractors and suppliers from 46 states and up to 95,000 jobs, and spanned 15 years at a peak rate of roughly two airplanes per month. In 2006, the F-22 development team won the Collier Trophy, American aviation's most prestigious award. Due to the aircraft's advanced nature, contractors have been targeted by cyberattacks and technology theft.
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3 billion and procurement cost of $26.2 billion in fiscal year (FY) 1985 dollars, with production beginning in 1994. The 1990 Major Aircraft Review led by Secretary of Defense Dick Cheney reduced this to 648 aircraft beginning in 1996. By 1997, funding instability had further cut the total to 339, which was again reduced to 277 by 2003. In 2004, the Department of Defense (DoD) further reduced this to 183 operational aircraft, despite the USAF's preference for 381. A multi-year procurement plan was implemented in 2006 to save $15 billion, with total program cost projected to be $62 billion for 183 F-22s distributed to seven combat squadrons. In 2008, Congress passed a defense spending bill that raised the total orders for production aircraft to 187.
The first two F-22s built were EMD aircraft in the Block 1.0 configuration for initial flight testing, while the third was a Block 2.0 aircraft built to represent the internal structure of production airframes and enabled it to test full flight loads. Six more EMD aircraft were built in the Block 10 configuration for development and upgrade testing, with the last two considered essentially production quality jets. Production for operational squadrons consisted of 37 Block 20 training aircraft and 149 Block 30/35 combat aircraft; one of the Block 35 aircraft is dedicated to flight sciences at Edwards Air Force Base.
The numerous new technologies in the F-22 resulted in substantial cost overruns and delays. Many capabilities were deferred to post-service upgrades, reducing the initial cost but increasing total program cost. As production wound down in 2011, the total program cost is estimated to be about $67.3 billion, with $32.4 billion spent on Research, Development, Test and Evaluation (RDT&E) and $34.9 billion on procurement and military construction (MILCON) in then year dollars. The incremental cost for an additional F-22 was estimated at about $138 million in 2009.
Ban on exports
The F-22 cannot be exported under US federal law to protect its stealth technology and other high-tech features. Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export. In September 2006, Congress upheld the ban on foreign F-22 sales. Despite the ban, the 2010 defense authorization bill included provisions requiring the DoD to prepare a report on the costs and feasibility for an F-22 export variant, and another report on the effect of F-22 export sales on U.S. aerospace industry.
Some Australian politicians and defense commentators proposed that Australia should attempt to purchase F-22s instead of the planned F-35s, citing the F-22's known capabilities and F-35's delays and developmental uncertainties. However, the Royal Australian Air Force (RAAF) determined that the F-22 was unable to perform the F-35's strike and close air support roles. The Japanese government also showed interest in the F-22 for its Replacement-Fighter program. The Japan Air Self-Defense Force (JASDF) would reportedly require fewer fighters for its mission if it obtained the F-22, thus reducing engineering and staffing costs. However, in 2009 it was reported that acquiring the F-22 would require increases to the Japanese government's defense budget beyond the historical 1 percent of its GDP. With the end of F-22 production, Japan chose the F-35 in December 2011. Israel also expressed interest, but eventually chose the F-35 because of the F-22's price and unavailability.
Production termination
Throughout the 2000s, the need for F-22s was debated, due to rising costs and the lack of relevant adversaries. In 2006, Comptroller General of the United States David Walker found that "the DoD has not demonstrated the need" for more investment in the F-22, and further opposition to the program was expressed by Secretary of Defense Donald Rumsfeld, Deputy Secretary of Defense Gordon R. England, Senator John McCain, and Chairman of U.S. Senate Committee on Armed Services Senator John Warner. The F-22 program lost influential supporters in 2008 after the forced resignations of Secretary of the Air Force Michael Wynne and the Chief of Staff of the Air Force General T. Michael Moseley.
In November 2008, Secretary of Defense Robert Gates stated that the F-22 was not relevant in post-Cold War conflicts such as irregular warfare operations in Iraq and Afghanistan, and in April 2009, under the new Obama Administration, he called for ending production in FY2011, leaving the USAF with 187 production aircraft. In July, General James Cartwright, Vice Chairman of the Joint Chiefs of Staff, stated to the Senate Committee on Armed Services his reasons for supporting termination of F-22 production. They included shifting resources to the multirole F-35 to allow proliferation of fifth-generation fighters for three service branches and preserving the F/A-18 production line to maintain the military's electronic warfare (EW) capabilities in the Boeing EA-18G Growler.[60] Issues with the F-22's reliability and availability also raised concerns. After President Obama threatened to veto further production, the Senate voted in July 2009 in favor of ending production and the House subsequently agreed to abide by the 187 production aircraft cap. Gates stated that the decision was taken in light of the F-35's capabilities, and in 2010, he set the F-22 requirement to 187 aircraft by lowering the number of major regional conflict preparations from two to one.
In 2010, USAF initiated a study to determine the costs of retaining F-22 tooling for a future Service Life Extension Program (SLEP).[66] A RAND Corporation paper from this study estimated that restarting production and building an additional 75 F-22s would cost $17 billion, resulting in $227 million per aircraft, or $54 million higher than the flyaway cost. Lockheed Martin stated that restarting the production line itself would cost about $200 million. Production tooling and associated documentation were subsequently stored at the Sierra Army Depot, allowing the retained tooling to support the fleet life cycle. There were reports that attempts to retrieve this tooling found empty containers, but a subsequent audit found that the tooling was stored as expected.
Russian and Chinese fighter developments have fueled concern, and in 2009, General John Corley, head of Air Combat Command, stated that a fleet of 187 F-22s would be inadequate, but Secretary Gates dismissed General Corley's concern. In 2011, Gates explained that Chinese fifth-generation fighter developments had been accounted for when the number of F-22s was set, and that the U.S. would have a considerable advantage in stealth aircraft in 2025, even with F-35 delays. In December 2011, the 195th and final F-22 was completed out of 8 test EMD and 187 operational aircraft produced; the aircraft was delivered to the USAF on 2 May 2012.
In April 2016, the House Armed Services Committee (HASC) Tactical Air and Land Forces Subcommittee proposed legislation that would direct the Air Force to conduct a cost study and assessment associated with resuming production of the F-22. Since the production halt directed in 2009 by then Defense Secretary Gates, lawmakers and the Pentagon noted that air warfare systems of Russia and China were catching up to those of the U.S. Lockheed Martin has proposed upgrading the Block 20 training aircraft into combat-coded Block 30/35 versions as a way to increase numbers available for deployment. On 9 June 2017, the Air Force submitted their report to Congress stating they had no plans to restart the F-22 production line due to economic and operational issues; it estimated it would cost approximately $50 billion to procure 194 additional F-22s at a cost of $206–$216 million per aircraft, including approximately $9.9 billion for non-recurring start-up costs and $40.4 billion for aircraft procurement costs.
Upgrades
The first aircraft with combat-capable Block 3.0 software flew in 2001. Increment 2, the first upgrade program, was implemented in 2005 for Block 20 aircraft onward and enabled the employment of Joint Direct Attack Munitions (JDAM). Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward are fitted with this radar, which incorporates air-to-ground modes. Increment 3.1 for Block 30 aircraft onward provided improved ground-attack capability through synthetic aperture radar mapping and radio emitter direction finding, electronic attack and Small Diameter Bomb (SDB) integration; testing began in 2009 and the first upgraded aircraft was delivered in 2011. To address oxygen deprivation issues, F-22s were fitted with an automatic backup oxygen system (ABOS) and modified life support system starting in 2012.
Increment 3.2 for Block 35 aircraft is a two-part upgrade process; 3.2A focuses on electronic warfare, communications and identification, while 3.2B includes geolocation improvements and a new stores management system to show the correct symbols for the AIM-9X and AIM-120D.[83][84] To enable two-way communication with other platforms, the F-22 can use the Battlefield Airborne Communications Node (BACN) as a gateway. The planned Multifunction Advanced Data Link (MADL) integration was cut due to development delays and lack of proliferation among USAF platforms. The F-22 fleet is planned to start receiving Increment 3.2B as well as a software upgrade for cryptography capabilities and avionics stability in May 2019. A Multifunctional Information Distribution System-Joint (MIDS-J) radio that replaces the current Link-16 receive-only box is expected to be operational by 2020. Subsequent upgrades are also focusing on having an open architecture to enable faster future enhancements.
In 2024, funding is projected to begin for the F-22 mid-life upgrade (MLU), which is expected to include new sensors and antennas, hardware refresh, cockpit improvements, and a helmet mounted display and cuing system. Other enhancements being developed include IRST functionality for the AN/AAR-56 Missile Launch Detector (MLD) and more durable stealth coating based on the F-35's.
The F-22 was designed for a service life of 8,000 flight hours, with a $350 million "structures retrofit program". Investigations are being made for upgrades to extend their useful lives further. In the long term, the F-22 is expected to be superseded by a sixth-generation jet fighter to be fielded in the 2030s.
Design
Overview
The F-22 Raptor is a fifth-generation fighter that is considered fourth generation in stealth aircraft technology by the USAF.[91] It is the first operational aircraft to combine supercruise, supermaneuverability, stealth, and sensor fusion in a single weapons platform. The F-22 has four empennage surfaces, retractable tricycle landing gear, and clipped delta wings with reverse trailing edge sweep and leading edge extensions running to the upper outboard corner of the inlets. Flight control surfaces include leading-edge flaps, flaperons, ailerons, rudders on the canted vertical stabilizers, and all-moving horizontal tails (stabilators); for speed brake function, the ailerons deflect up, flaperons down, and rudders outwards to increase drag.
The aircraft's dual Pratt & Whitney F119-PW-100 augmented turbofan engines are closely spaced and incorporate pitch-axis thrust vectoring nozzles with a range of ±20 degrees; each engine has maximum thrust in the 35,000 lbf (156 kN) class. The F-22's thrust-to-weight ratio at typical combat weight is nearly at unity in maximum military power and 1.25 in full afterburner. Maximum speed without external stores is approximately Mach 1.8 at military power and greater than Mach 2 with afterburners.
The F-22's high cruise speed and operating altitude over prior fighters improve the effectiveness of its sensors and weapon systems, and increase survivability against ground defenses such as surface-to-air missiles. The aircraft is among only a few that can supercruise, or sustain supersonic flight without using fuel-inefficient afterburners; it can intercept targets which subsonic aircraft would lack the speed to pursue and an afterburner-dependent aircraft would lack the fuel to reach. The F-22's thrust and aerodynamics enable regular combat speeds of Mach 1.5 at 50,000 feet (15,000 m). The use of internal weapons bays permits the aircraft to maintain comparatively higher performance over most other combat-configured fighters due to a lack of aerodynamic drag from external stores. The aircraft's structure contains a significant amount of high-strength materials to withstand stress and heat of sustained supersonic flight. Respectively, titanium alloys and composites comprise 39% and 24% of the structural weight.
The F-22's aerodynamics, relaxed stability, and powerful thrust-vectoring engines give it excellent maneuverability and energy potential across its flight envelope. The airplane has excellent high alpha (angle of attack) characteristics, capable of flying at trimmed alpha of over 60° while maintaining roll control and performing maneuvers such as the Herbst maneuver (J-turn) and Pugachev's Cobra. The flight control system and full-authority digital engine control (FADEC) make the aircraft highly departure resistant and controllable, thus giving the pilot carefree handling.
Stealth
The F-22 was designed to be highly difficult to detect and track by radar. Measures to reduce radar cross-section (RCS) include airframe shaping such as alignment of edges, fixed-geometry serpentine inlets and curved vanes that prevent line-of-sight of the engine faces and turbines from any exterior view, use of radar-absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return. The F-22 was also designed to have decreased radio emissions, infrared signature and acoustic signature as well as reduced visibility to the naked eye. The aircraft's flat thrust-vectoring nozzles reduce infrared emissions of the exhaust plume to mitigate the threat of infrared homing ("heat seeking") surface-to-air or air-to-air missiles. Additional measures to reduce the infrared signature include special topcoat and active cooling of leading edges to manage the heat buildup from supersonic flight.
Compared to previous stealth designs like the F-117, the F-22 is less reliant on RAM, which are maintenance-intensive and susceptible to adverse weather conditions. Unlike the B-2, which requires climate-controlled hangars, the F-22 can undergo repairs on the flight line or in a normal hangar. The F-22 has a Signature Assessment System which delivers warnings when the radar signature is degraded and necessitates repair. While the F-22's exact RCS is classified, in 2009 Lockheed Martin released information indicating that from certain angles the aircraft has an RCS of 0.0001 m² or −40 dBsm – equivalent to the radar reflection of a "steel marble". Effectively maintaining the stealth features can decrease the F-22's mission capable rate to 62–70%.
The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of Rayleigh scattering and resonance mean that low-frequency radars such as weather radars and early-warning radars are more likely to detect the F-22 due to its physical size. However, such radars are also conspicuous, susceptible to clutter, and have low precision. Additionally, while faint or fleeting radar contacts make defenders aware that a stealth aircraft is present, reliably vectoring interception to attack the aircraft is much more challenging. According to the USAF an F-22 surprised an Iranian F-4 Phantom II that was attempting to intercept an American UAV, despite Iran's assertion of having military VHF radar coverage over the Persian Gulf.
Corfe Castle is a fortification standing above the village of the same name on the Isle of Purbeck in the English county of Dorset. Built by William the Conqueror, the castle dates to the 11th century and commands a gap in the Purbeck Hills on the route between Wareham and Swanage. The first phase was one of the earliest castles in England to be built at least partly using stone when the majority were built with earth and timber. Corfe Castle underwent major structural changes in the 12th and 13th centuries.
In 1572, Corfe Castle left the Crown's control when Elizabeth I sold it to Sir Christopher Hatton. Sir John Bankes bought the castle in 1635, and was the owner during the English Civil War. His wife, Lady Mary Bankes, led the defence of the castle when it was twice besieged by Parliamentarian forces. The first siege, in 1643, was unsuccessful, but by 1645 Corfe was one of the last remaining royalist strongholds in southern England and fell to a siege ending in an assault. In March that year Corfe Castle was slighted on Parliament's orders. Owned by the National Trust, the castle is open to the public and in 2017 received around 247,000 visitors. It is protected as a Grade I listed building and a Scheduled Ancient Monument.
Corfe Castle was built on a steep hill in a gap in a long line of chalk hills, created by two streams eroding the rock on either side. The name Corfe derives from the Old English ceorfan, meaning 'a cutting', referring to the gap. The construction of the medieval castle means that little is known about previous activity on the hill. However, there are postholes belonging to a Saxon hall on the site. The hall may be where the boy-king Edward the Martyr was assassinated in 978.
A castle was founded at Corfe on England's south coast soon after the Norman Conquest of England in 1066. The royal forest of Purbeck, where William the Conqueror enjoyed hunting, was established in the area. Between 1066 and 1087, William established 36 such castles in England. Sitting as it does on a hill top, Corfe Castle is one of the classic images of a medieval castle. However, despite popular imagination, occupying the highest point in the landscape was not the typical position of a medieval castle. In England, a minority are located on hilltops, but most are in valleys; many were near important transport routes such as river crossings.
Unusually for castles built in the 11th century, Corfe was partially constructed from stone indicating it was of particularly high status. A stone wall was built around the hill top, creating an inner ward or enclosure. There were two further enclosures: one to the west, and one that extended south (the outer bailey); in contrast to the inner bailey, these were surrounded by palisades made from timber. At the time, the vast majority of castles in England were built using earth and timber, and it was not until the 12th century that many began to be rebuilt in stone. The Domesday Book records one castle in Dorset; the entry, which reads "Of the manor of Kingston the King has one hide on which he built Wareham castle", is thought to refer to Corfe rather than the timber castle at Wareham. There are 48 castles directly mentioned in the Domesday Book, although not all those in existence at the time were recorded. Assuming that Corfe is the castle in question, it is one of four the Domesday Book attributes to William the Conqueror; the survey explicitly mentions seven people as having built castles, of which William was the most prolific.
In the early 12th century, Henry I began the construction of a stone keep at Corfe. Progressing at a rate of 3 to 4 metres (10 to 13 ft) per year for the best part of a decade, the work was complete by 1105. The chalk of the hill Corfe Castle was built on was an unsuitable building material, and instead Purbeck limestone quarried a few miles away was used. By the reign of King Stephen (1135–1154) Corfe Castle was already a strong fortress with a keep and inner enclosure, both built in stone. In 1139, during the civil war of Stephen's reign, Corfe withstood a siege by the king. It is thought that he built a siege castle to facilitate the siege and that a series of earthworks about 290 metres (320 yd) south-southwest of Corfe Castle mark the site of the fortification.
During the reign of Henry II Corfe Castle was probably not significantly changed, and records from Richard I's reign indicate maintenance rather than significant new building work. In contrast, extensive construction of other towers, halls and walls occurred during the reigns of John and Henry III, both of whom kept Eleanor, rightful Duchess of Brittany who posed a potential threat to their crowns, in confinement at Corfe until 1222. It was probably during John's reign that the Gloriette in the inner bailey was built. The Pipe Rolls, records of royal expenditure, show that between 1201 and 1204 over £750 was spent at the castle, probably on rebuilding the defences of the west bailey with £275 spent on constructing the Gloriette. The Royal Commission on the Historical Monuments of England noted the link between periods of unrest and building at Corfe. In the early years of his reign, John lost Normandy to the French, and further building work at Corfe coincided with the political disturbances later in his reign. At least £500 was spent between 1212 and 1214 and may have been focused on the defences of the outer bailey. R. Allen Brown noted that in John's reign "it would seem that though a fortress of the first order might cost more than £7,000, a medium castle of reasonable strength might be built for less than £2,000". The Pipe Rolls show that John spent over £17,000 on 95 castles during his reign spread; he spent over £500 at nine of them, of which Corfe was one. Additional records show that John spent over £1,400 at Corfe Castle.
One of the secondary roles of castles was to act as a storage facility, as demonstrated by Corfe Castle; in 1224 Henry III sent to Corfe for 15,000 crossbow bolts to be used in the siege of Bedford Castle. Following John's work, Henry III also spent over £1,000 on Corfe Castle, in particular the years 1235 and 1236 saw £362 spent on the keep. While construction was under-way, a camp to accommodate the workers was established outside the castle. Over time, this grew into a settlement in its own right and in 1247 was granted a market and fair by royal permission. It was Henry III who ordered in 1244 that Corfe's keep should be whitewashed. Four years previously, he also ordered that the keep of the Tower of London should be whitewashed, and it therefore became known as the White Tower.
In December 1460, during the Wars of the Roses Henry Beaufort and his army marched from the castle destined for the Battle of Wakefield. During the march the army split at Exeter so the cavalry could reach the north quicker, and on 16 December 1460 some of his men became embroiled in the Battle of Worksop, Nottinghamshire. Beaufort and the Lancastrians won the skirmish.
The castle remained a royal fortress until sold by Elizabeth I in 1572 to her Lord Chancellor, Sir Christopher Hatton. Ralph Treswell, Hatton's steward, drafted a series of plans of the castle; the documents are the oldest surviving survey of the castle.
The castle was bought by Sir John Bankes, Attorney General to Charles I, in 1635. The English Civil War broke out in 1642, and by 1643 most of Dorset was under Parliamentarian control. While Bankes was in Oxford with the king, his men held Corfe Castle in the royal cause. During this time his wife, Lady Mary Bankes, resided at the castle with their children. Parliamentarian forces planned to infiltrate the castle's garrison by joining a hunting party from the garrison on a May Day hunt; however they were unsuccessful. The Parliamentarians gave orders that anyone joining the garrison would have their house burned and that no supplies were to reach the castle. Initially defended by just five people, Lady Bankes was able to get food through and swell the garrison to 80. The Parliamentarian forces numbered between 500 and 600 and began a more thorough siege; it went on for six weeks until Lady Bankes was relieved by Royalist forces. During the siege the defenders suffered two casualties while there were at least 100 deaths among the besieging force.
The Parliamentarians were in the ascendency so that by 1645 Corfe Castle was one of a few remaining strongholds in southern England that remained under royal control. Consequently, it was besieged by a force under the command of a Colonel Bingham. One of the garrison's officers, Colonel Pitman, colluded with Bingham. Pitman proposed that he should go to Somerset and bring back a hundred men as reinforcements; however the troops he returned with were Parliamentarians in disguise. Once inside, they waited until the besieging force attacked before making a move, so that the defenders were attacked from without and within at the same time. Corfe Castle was captured and Lady Bankes and the garrison were allowed to leave. In March that year, Parliament voted to slight (demolish) the castle, giving it its present appearance. In the 17th century many castles in England were in a state of decline, but the war saw them pressed into use as fortresses one more time. Parliament ordered the slighting of many of these fortifications, but the solidity of their walls meant that complete demolition was often impracticable. A minority were repaired after the war, but most were left as ruins. Corfe Castle provided a ready supply of building material, and its stones were reused by the villagers.
After the restoration of the monarchy in 1660, the Bankes family regained their properties. Rather than rebuild or replace the ruined castle they chose to build a new house at Kingston Lacy on their other Dorset estate near Wimborne Minster.
The first archaeological excavations were carried out in 1883. No further archaeological work was carried out on the site until the 1950s. Between 1986 and 1997 excavations were carried out, jointly funded by the National Trust and English Heritage. Corfe Castle is considered to be the inspiration for Enid Blyton's Kirrin Island, which had its own similar castle. It was used as a shooting location for the 1957 film Five on a Treasure Island (film) and the 1971 film Bedknobs and Broomsticks. The castle plays an important part in Keith Roberts' uchronia novel Pavane.
Upon his death, Henry John Ralph Bankes (1902–81) bequeathed the entire Bankes estate to the National Trust, including Corfe Castle, much of the village of Corfe, the family home at Kingston Lacy, and substantial property and land holdings elsewhere in the area.
In summer 2006, the dangerous condition of the keep caused it to be closed to visitors, who could only visit the walls and inner bailey. The National Trust undertook an extensive conservation project on the castle, and the keep was re-opened to visitors in 2008, and the work completed the following year. During the restoration work, an "appearance" door was found in the keep, designed for Henry I. The National Trust claims that this indicates that the castle would have been one of the most important in England at the time.
The castle is a Grade I listed building, and recognised as an internationally important structure. It is also a Scheduled Monument, a "nationally important" historic building and archaeological site which has been given protection against unauthorised change. The earthworks known as "The Rings", thought to be the remains of a 12th-century motte-and-bailey castle built during a siege of Corfe are also scheduled. In 2006, Corfe Castle was the National Trust's tenth most-visited historic house with 173,829 visitors. According to figures released by the Association of Leading Visitor Attractions, the number of visitors in 2010 had risen to nearly 190,000.

Corfe Castle ist die Ruine einer Burg im englischen Ort Corfe Castle in der Grafschaft Dorset. Die als Kulturdenkmal der Kategorie Grade I klassifizierte und als Scheduled Monument geschützte Ruine liegt in den Purbeck Hills auf der Isle of Purbeck sieben Kilometer südöstlich von Wareham und acht Kilometer westlich von Swanage. Es liegt etwa 12 km südwestlich der großen Städte Poole und Bournemouth.
Der Bezeichnung Corfe kommt aus dem Angelsächsischen und bezeichnet das Tal, in dem sich das Dorf und die Burgruine befindet. Corfe Castle bedeutet übersetzt also ungefähr Talburg oder Burg im Tal.
Unter Alfred dem Großen wurde Ende des 9. Jahrhunderts zum Schutz vor den Dänen in Corfe eine erste Befestigung angelegt. Der Legende nach wurde der englische König Eduard der Märtyrer am 18. März 978 in der Burg ermordet.
Nach der normannischen Eroberung Englands wurde um 1090 von den Normannen am Ort der alten Befestigungsanlage der Bau einer Burg aus dem lokalen Kalkstein begonnen. Unter Henry I. „Beauclerc“ entstand um 1105 der mächtige Keep. Zu Beginn des englischen Bürgerkriegs wurde die Burg, die von Baldwin de Redvers verteidigt wurde, 1139 erfolglos von König Stephan belagert. Unter König Johann Ohneland wurde die Burg weiter ausgebaut. Er hielt sich häufig in der Burg auf, außerdem nutzte er sie als Aufbewahrungsort für die Kronjuwelen und als Gefängnis. 1202 kam es zu einem Ausbruchsversuch von 25 französischen Rittern, die während des Französisch-Englischen Krieges gefangen genommen worden waren. Sie konnten jedoch nur den Keep besetzen, in dem sie lieber verhungerten, anstatt sich zu ergeben. 22 der Ritter starben, nur drei Überlebende konnten schließlich überwältigt werden. Auch Johanns Nichte Eleonore von der Bretagne und im 14. Jahrhundert König Eduard II. wurden in Corfe Castle gefangen gehalten. Unter Eduard I. wurde der äußere Burghof vollendet. Im 14. Jahrhundert wurde die Burg zunächst vernachlässigt, bis Eduard III. sie zwischen 1356 und 1377 instand setzen ließ. Nach den Rosenkriegen ließ sie Heinrich VII. als Residenz für seine Mutter Margaret Beaufort ausbauen. Nach deren Tod fiel die Burg wieder zurück an die Krone. 1572 verkaufte Elisabeth I. sie an ihren späteren Lordkanzler Christopher Hatton, der die Burg angesichts der Bedrohung durch die spanische Armada weiter befestigte. 1635 erwarb Sir John Bankes, der spätere Chief Justices of the Common Pleas, die Burg.
Im Jahr 1643, während des Englischen Bürgerkrieges, wurde die Burg von Truppen der Parlamentarier („Roundheads“) belagert. Unter dem Befehl der Royalistin Lady Mary Bankes hielt die Burg der Belagerung für sechs Wochen stand, woraufhin sich die Parlamentarier mit einem Verlust von 100 Männern zurückzogen. Drei Jahre später, 1646, wurde die Burg ein zweites Mal belagert. Nach zweimonatiger Belagerung wurde die Burggarnison im Februar 1646 von einem ihrer Mitglieder verraten. Nach der Übernahme durch die Parlamentarier wurde der Familie der Bankes erlaubt, die Burg zu verlassen. Die Burg wurde daraufhin von Sappeuren mit Sprengstoff zerstört, was zum heutigen Aussehen der Burganlage führte. Die örtliche Bevölkerung nutzte dies aus und verwertete die aus der Burg stammenden Steine, Türrahmen usw. für ihre nahe gelegenen Häuser.
Nach dem Bürgerkrieg errichtete Ralph Bankes 1663 bei Wimborne Minster Kingston Hall als neuen Familiensitz. Die Überreste von Corfe Castle blieben bis 1982 im Besitz der Bankes-Familie, dann überließ sie Ralph Bankes dem National Trust, der britischen Treuhand-Organisation für Denkmalpflege. Nach Einsturzgefahr des Bergfrieds im Jahre 2006 sind die oberen Ruinen jetzt wieder zu besichtigen.
Die Burg ist Eigentum des National Trust, der am Marktplatz auch einen Souvenirladen eingerichtet hat. 2002 zählte die ganzjährig für Touristen zugängliche Burg 167.582 Besucher.
Am Marktplatz von Corfe Castle steht das Corfe Model Village mit einer Nachbildung der Burg und des Dorfes vor der Zerstörung in einem Maßstab von 1:20. Es wurde von 1964 bis 1966 von Eddie Holland erstellt.
Die Ruine diente u. a. als Kulisse für die Fernsehserie Die Sache mit der Schatzinsel, die 1957 nach Motiven der Kinderbuchreihe Fünf Freunde von Enid Blyton gedreht wurde, sowie für die 2008 gedrehte Verfilmung des Romans Tess von den d’Urbervilles.
