The largest known cave system in the world, the Mammoth-Flint Ridge Cave System, as of 2022, has 426 miles of documented passages, and sits beneath the ground in Mammoth Cave National Park, established in 1941, and was listed as a UNESCO World Heritage Site in 1981, the only designation in the state of Kentucky. The park is also an International Biosphere Reserve, designated in 1990, and an International Dark Sky Park, designated in 2021. The Mammoth-Flint Ridge Cave System formed in Mississippian Limestone rock underneath a Big Clifty Sandstone cap, which has formed several stable arched passages of varying sizes from the intrusion of water into the rock layers, with the less porous sandstone cap preventing water intrusion at most locations, which have kept the caverns beneath intact and stable for eons. The water that passes through the cave system drains into the adjacent Green River, and has continuously eroded deeper into the rock along with the river. The cave is home to endemic species of organisms that have adapted to the dark conditions within the cave system. The cave system was known to indigenous people, whom mined gypsum from the walls of the caves and explored the caves, with human remains, signs of human activity, and artifacts from their presence in the cave. The cave became known to European settlers in the 1790s, and it started being mined by Valentine Simon for saltpeter to create gunpowder in 1798, with the mining activities intensifying around the time of the War of 1812, and becoming an industrial-scale operation under the ownership of Charles Wilkins and Hyman Gratz, whom used slave labor to exploit the cave’s resources. In 1838, with the decline in value of saltpeter, the cave was sold to Franklin Gorin, whom operated the cave as a tourist attraction, but was sold to Doctor John Croghan the following year. Under Gorin and Croghan, Black slaves served as tour guides for visitors, with Stephen Bishop being the most notable of these guides. Bishop made many maps of the caves during the 1840s and 1850s, and was the first known person to cross Bottomless Pit and discover the River Styx and Mammoth Dome on the other side. Croghan attempted to run a Tuberculosis Hospital within the cave in 1842-1843, believing the stable temperatures and air would assist patients, but this was short lived. In 1886, the Mammoth Cave Railroad was built between Park City and the historic Mammoth Cave Hotel, which operated until 1931. The caves were mapped more accurately by German visitor Max Kämper in 1908, whom mapped the surface topography and used instruments to document the cave, allowing for the opening of new entrances to the caverns from the surface and being the most accurate maps of the caves until the 1960s. Sadly, this was not appreciated by the Croghan family, whose historic cavern entrance was threatened in status by these maps, and Kämper returned to Germany, where he died as a soldier during World War I’s Battle of the Somme in 1916. Starting in the 1920s, the land around the caves was purchased by the private Mammoth Cave National Park Association, with the park being officially authorized in 1926. Between 1933 and 1942, the park’s landscape was reforested and infrastructure was constructed by the Civilian Conservation Corps (CCC), part of the New Deal. Between 1954 and 1972, the cave system was further explored, culminating in the connection between the longer Flint Ridge System and wider Mammoth Cave being found, making it the longest known cave system in the world. Today, the park sees about half a million visitors annually, and contains the majority of the Mammoth-Flint Ridge Cave system, with some portions of the system extending east of the park’s boundaries under privately-owned land.

San Antonio Missions National Historical Park - San Antonio, Texas

"Mission San José y San Miguel de Aguayo is a historic Catholic mission in San Antonio, Texas, USA. The mission was named in part for the Marquis de San Miguel de Aguayo, José de Azlor y Virto de Vera. Many buildings on the campus of Texas Tech University in Lubbock, Texas, borrow architectural elements from those found at Mission San José.

The mission was founded on February 23, 1720, because Mission San Antonio de Valero had become overcrowded shortly after its founding with refugees from the closed East Texas missions. Father Antonio Margil received permission from the governor of Coahuila and Texas, the Marquis de San Miguel de Aguayo, to build a new mission 5 miles (8 km) south of San Antonio de Valero. Like San Antonio de Valero, Mission San José served the Coahuiltecan Indians. The first buildings, made of brush, straw, and mud, were quickly replaced by large stone structures, including guest rooms, offices, a dining room, and a pantry. A heavy outer wall was built around the main part of the mission, and rooms for 350 Indians were built into the walls.

A new church, which is still standing, was constructed in 1768 from local limestone.[4] The mission lands were given to its Indians in 1794, and mission activities officially ended in 1824. After that, the buildings were home to soldiers, the homeless, and bandits. Starting in 1933, the Civil Works Administration and then the Works Progress Administration provided the labor to rebuild and restore the grounds of the mission. Some of the funding for the restoration came from money allotted by the United States for the Texas Centennial Exposition held in Dallas in 1936. The mission walls and Indian quarters were re-built, and the granary was restored.

Mission San José is now part of the San Antonio Missions National Historical Park. In 2015, along with The Alamo and Mission Concepcion, it became one of five missions in San Antonio designated a World Heritage Site by the United Nations Education, Scientific and Cultural Organization."

The second stop on our tour of Rabat, Morocco, was the complex of the modern Mausoleum of Mohammed V and the 12th century Hassan Tower. Construction of the Hassan Tower stopped with the commissioning caliph died, and all that stands is the minaret and some traces of the walls. The modern columns mark the area that the mosque would have filled, and the Mausoleum of Mohammed V occupies the other end of the space.

The tower of Church of St. Nicholas and Benedictine convent (both of which date back to the 11th century) was rebuilt in the 16th century.

I traveled to India for the first time to present a keynote at the 3rd Global Conference on Emerging Trends for Business Librarianship, November 21-22, 2017 at the Indian Institute of Management - Ahmedabad, India. We did some sightseeing on our last day in India and visited the amazing Rani ki vav stepwell near Patan, north of Ahmedabad. I am so very glad that I made it here. From the Wikipedia page, "Rani ki vav, or Ran-ki vav (Queen’s step well) was constructed during the rule of the Chaulukya dynasty. It is generally assumed that it was built in the memory of Bhima I (r. c. 1022–1064) by his widowed queen Udayamati and probably completed by Udayamati and Karna after his death. A reference to Udayamati building the monument is in Prabandha Chintamani, composed by the Jain monk Merunga Suri in 1304 AD." The term vav is Gujarati for stepwell.

San Antonio Missions National Historical Park - San Antonio, Texas

April 27, 2013

"Mission San Francisco de la Espada (also Mission Espada) is a Roman Rite Catholic mission established in 1690 by Spain in present-day San Antonio, Texas, in what was then known as northern New Spain. The mission was built in order to convert local Native Americans to Christianity and solidify Spanish territorial claims in the New World against encroachment from France. Today, the structure is one of four missions that comprise San Antonio Missions National Historical Park.

Founded in 1690 as San Francisco de los Tejas near Weches, Texas and southwest of present-day Alto, Texas, Mission San Francisco de la Espada was the first mission established in Texas.

Three priests, three soldiers and supplies left among the Nabedache Indians. The new mission was dedicated on June 1, 1690. A smallpox epidemic in the winter of 1690-1691 killed an estimated 3,300 people in the area. The Nabedache believed the Spaniards brought the disease and hostilities developed between the two groups.

Drought besieged the mission in the summers of 1691 and 1692, and the Nabedache wished to get rid of the mission. Under threat of personal attack, the priests began packing their belongings in the fall of 1693. On October 25, 1693, the padres burned the mission and retreated toward Monclova. The party lost its way and did not reach Monclova until February 17, 1694.

The mission was re-established in the same area on July 5, 1716 as Nuestro Padre San Francisco de los Tejas. The new mission had to be abandoned in 1719 because of conflict between Spain and France.

The mission was tried once more on August 5, 1721 as San Francisco de los Neches. As the Nabedache were no longer interested in the mission, and France had abandoned effort to lay claim in the area, the mission was temporarily relocated along the Colorado River in July 1730. Mission Tejas State Park encompasses the original site of the mission.

The mission relocated to its current location in the San Antonio River area in March, 1731 and was renamed San Francisco De la Espada. A friary was built in 1745, and the church was completed in 1756. The relocation was in part inspired by fears of French encroachment and need for more Missionaries to tend to San Antonio de Bexar's Indian population. The Mission encountered great difficulties in presiding over the Indian population and experienced common rebellious activity."

Believed to be the longest herbaceous borders in the country – and possibly in the world – our Great Broad Walk Borders stretch out in a rainbow of colour.

At more than 320 metres, the borders offer an adventure for the senses – with fresh fragrances, dazzling flower beds and feathery grasses in a joyful display that evolves with the seasons.

Originally designed as an impressive promenade to the Palm House, the borders were replanted in 2016. Arranged in themes across eight large circular beds, they showcase a spectacular range of plant families – ideal inspiration for your own garden.

The largest known cave system in the world, the Mammoth-Flint Ridge Cave System, as of 2022, has 426 miles of documented passages, and sits beneath the ground in Mammoth Cave National Park, established in 1941, and was listed as a UNESCO World Heritage Site in 1981, the only designation in the state of Kentucky. The park is also an International Biosphere Reserve, designated in 1990, and an International Dark Sky Park, designated in 2021. The Mammoth-Flint Ridge Cave System formed in Mississippian Limestone rock underneath a Big Clifty Sandstone cap, which has formed several stable arched passages of varying sizes from the intrusion of water into the rock layers, with the less porous sandstone cap preventing water intrusion at most locations, which have kept the caverns beneath intact and stable for eons. The water that passes through the cave system drains into the adjacent Green River, and has continuously eroded deeper into the rock along with the river. The cave is home to endemic species of organisms that have adapted to the dark conditions within the cave system. The cave system was known to indigenous people, whom mined gypsum from the walls of the caves and explored the caves, with human remains, signs of human activity, and artifacts from their presence in the cave. The cave became known to European settlers in the 1790s, and it started being mined by Valentine Simon for saltpeter to create gunpowder in 1798, with the mining activities intensifying around the time of the War of 1812, and becoming an industrial-scale operation under the ownership of Charles Wilkins and Hyman Gratz, whom used slave labor to exploit the cave’s resources. In 1838, with the decline in value of saltpeter, the cave was sold to Franklin Gorin, whom operated the cave as a tourist attraction, but was sold to Doctor John Croghan the following year. Under Gorin and Croghan, Black slaves served as tour guides for visitors, with Stephen Bishop being the most notable of these guides. Bishop made many maps of the caves during the 1840s and 1850s, and was the first known person to cross Bottomless Pit and discover the River Styx and Mammoth Dome on the other side. Croghan attempted to run a Tuberculosis Hospital within the cave in 1842-1843, believing the stable temperatures and air would assist patients, but this was short lived. In 1886, the Mammoth Cave Railroad was built between Park City and the historic Mammoth Cave Hotel, which operated until 1931. The caves were mapped more accurately by German visitor Max Kämper in 1908, whom mapped the surface topography and used instruments to document the cave, allowing for the opening of new entrances to the caverns from the surface and being the most accurate maps of the caves until the 1960s. Sadly, this was not appreciated by the Croghan family, whose historic cavern entrance was threatened in status by these maps, and Kämper returned to Germany, where he died as a soldier during World War I’s Battle of the Somme in 1916. Starting in the 1920s, the land around the caves was purchased by the private Mammoth Cave National Park Association, with the park being officially authorized in 1926. Between 1933 and 1942, the park’s landscape was reforested and infrastructure was constructed by the Civilian Conservation Corps (CCC), part of the New Deal. Between 1954 and 1972, the cave system was further explored, culminating in the connection between the longer Flint Ridge System and wider Mammoth Cave being found, making it the longest known cave system in the world. Today, the park sees about half a million visitors annually, and contains the majority of the Mammoth-Flint Ridge Cave system, with some portions of the system extending east of the park’s boundaries under privately-owned land.

Fallingwater is a renowned house designed by Frank Lloyd Wright in 1935, located in Mill Run, Pennsylvania. It is celebrated for its unique design that integrates with the natural landscape, being built partly over a waterfall on the Bear Run stream. Fallingwater is considered Wright's crowning achievement in organic architecture and has been recognized as the best all-time work of American architecture by the American Institute of Architects. The house was originally a private residence for the Kaufmann family and is now a museum, showcasing Wright's innovative approach to architecture and nature. It is also a UNESCO World Heritage site.
