This certainly isn't the prettiest photo I or anyone else has ever taken of this building's stunning interior. But it does at least remind me that my visit half a century ago took place at a time when some sort of restoration effort was underway. Hence the scaffolding in the foreground.
Though it was constructed well over a millennnium after the nearby Hagia Sophia, the Sultan Ahmed Mosque owes some of its main design features to it—or at least to Byzantine-church architecture in general. Of course, over the centuries this sort of artistic and engineering cross-fertilization between cultures and religions has proved to be a very heavily traveled two-way street.
One can easily rattle off the correspondences between those two great imperial-city structures. Here, for example, architect Sedefkâr Mehmed Ağa, a pupil of the great Sinan, utilized pendentives and half-domes supported by massive piers that transmit the weight of the main dome and all else down to the foundation and bedrock below.
Pendentives are curved, triangular sections of a sphere. One is is visible in this shot between two half-domes, at top. Lurking behind the scenes, in the walls and piers, are the main structural materials, brick and locally quarried, Miocene-epoch Bakırköy Limestone.
And speaking of stone: the one stout, upper-level column visible behind the scaffoling looks very much like Proconnesian Marble, quarried on Marmara Island in the sea of the same name since Roman times. The Mosque's mihrab is carved from that stone, and I assume it is also the ornamental rock type used in some of the columns. It may even be the marble of the ribbed sections of the famous elephant-foot piers. But so far I lack documentation for that.
The other geologically derived material on display is the ceramic İznik Tile. More on that in the images that follow!

Construction works in the new tunnel of Munich's city highway system. This is a tunnel crossing below another tunnel in a curve, making it a particular tricky task of civil engineering.

Scene captured during a day trip to the Waterloopbos in the Netherlands: a look at the Delta Works experimental setup in this open-air civil engineering laboratory now turned into a work of art.
I was recently bequeathed a box of materials from an ex-colleague who had, for many years, worked for British Rail. There's an eclectic mix of items including this; a file of five notes originating in the Chief Civil Engineers Department of British Railways Southern Region and regarding the movement of an "electric Bo-Bo locomotive" in connection with the Festival of Britain 1951. The major exhibition of the Festival was, famously, on London's South Bank and various items of railway rolling stock, including a new aluminium bodied London Underground car, were exhibited. This file refers to one of the country's newest and most 'up to date' locomotives in that it was one of the batch of EM1 locomotives being constructed for the new Manchester - Sheffield Woodhead route, the long drawn out electrification of which was on the verge of completion.
The scheme had been planned pre-war by the London & North Eastern Railway as an extensive re-engineering of the then important route across the Pennines but the outbreak of war saw the scheme temporarily suspended. One locomotive was however completed at Doncaster number 6701 (later 6000) and in post-war years was lent to the Dutch Railways. Finally between 1950 and 1953 57 similar locomotives, now known as class EM1 and for freight use, were built at Manchester's Gorton Works and electrically completed by Metropolitan-Vickers at Dunkinfield. You can see in the files that the special train including the locomotive was attended by MV staff.
The locomotive chosen for exhibition was 26020 (in later BR TOPS years 76020) and it was fitted with stainless steel handrails to make it look the part, a feature it uniquely retained amongst the rest of class. 26020 was in fact chosen for preservation when the class was withdrawn went the Woodhead electrification was controversially abandoned by BR in 1981. The seven locomotives of the smaller Class EM2 Co-Co locomotives for passenger train use were sold to NS, the Dutch Railway operator.
The notes show a fascinating side to railway operations; that of the civil engineer as they had to compute that any route chosen was safe, structurally and in terms of gauge, for the locomotive and train to proceed across the Region's lines. As can be seen originally two routes were considered, some rejected and others suggested, until a route was cleared. It does not make clear which route was eventually traversed to the old turntable site adjacent to London Waterloo but it appears the pantographs were removed to facilitate overhead clearances.
The route back at the close of the Exhibition is given more succinctly; a route around South London was chosen through London Bridge, Norbury, Clapham Junction, Battersea and on to the Western Region (for their consideration) near Latchmere Junction for haulage on to the 'owners' the Eastern Region at Ilford Depot. The latter is noteworthy as Iiford was part of the other pre-war LNER electrication scheme at the soon to be 'abandoned' standard of 1500vDC and the Shenfield line had been used to test some of the EM1 locomotives on delivery in 1950/51 prior to the completion of the Woodhead route's electrification in 1952.
One name here stands out to me; that of V A M Robertson. He had been a senior engineer in the Underground Group and London Transport from 1928 until 1938 when he went to the Southern Railway and thence to British Railways.

One of the East Leeds Link Road set.
Construction of this monster viaduct continues apace. Most people in Leeds don't seem to know that this is going on. Some roads are being closed off at the w/ends to allow the girders to be lifted into place.
Very early in the morning is a good time to go down, I saw at least one other snapper there.
One of the largest civil engineering projects in Leeds in recent years, yet it seems to be largely unnoticed.
The curves on this thing are insane.
Taken from the high viewing perch on the eastern side of the Aqueduct. Facing south.
In this image we're looking upstream, so to speak, and toward the water's distant source. The high ground in the back, accessed by the broad set of steps, is the Plaza de Dia Sanz. There a single-arcade Aqueduct makes a 45-degree turn into a swale where it becomes a much more impressive, double arcade structure.
Up there on the hill the Roman architects had the firm bedrock footing of Variscan (Late Palezoic) aplitic granite the same age as the Guadrarrama Granite they used for the Aqueduct itself. But in the low area, where the bridge piers and arches they carry weigh the most, they had to deal with softer, Upper Cretaceous sandstone instead.
As I noted in a previous description of this series, the foundation engineers who tackled that problem clearly knew what they were doing. There they carefully excavated socketlike pits into the substrate to give the piers more secure anchorage.

Opened in 1902. The tunnel runs under the Thames from the bottom of the Isle of Dogs to Greenwich. I'm delighted to discover that there is a group called "Friends of the Greenwich and Woolwich foot tunnels" or FOGWOFT.
I was inspired to re-visit the tunnel after seeing the picture posted by Past London:

which is still a better picture than mine IMHO
