I have been experimenting with a new lens (Laowa FF S 15mm). It is a shift lens and today I took photos of this enormous building with it.The photo below is made of two stitched photos taken without moving the camera. Take that last remark with a pinch of salt, as I was holding it in my hand. I took one photo and moved the lens sideways, taking a second shot. I later stitched these together in Photoshop. I still have a lot to learn about this technique, which I find very helpful for the shots I want to take.

It is not, perhaps a beautiful building, but an interesting one. It was opened on 1 May 1873 as the Hotel Donau, the same day as the opening of the Vienna World's Fair which was timed to celebrate the 25 year of the reign of Emperor Franz Joseph. The Fair ran for six months, attracting more than seven million visitors. A contemporary map of the locale is here.
The building was opposite the Nordbahnhof (North Railway Station). In 1907 the building was acquired by the State Railways, today the Austrian Federal Railways, as one can see from the ÖBB acronym on the doors (Österreichische Bundesbahnen). The Nordbahnhof was used until 1945 and, among others, many Jews passed through on their way to Theresienstadt or Auschwitz. There are plaques (Stolpersteine -- stumbling stones) in the sidewalk outside the main door in their memory.

"In memory of the many Jewish people, for whom the Nordbahnhof was supposed to be a gateway to a better life. They were banished, deported and murdered by the Nazis." Thise named probably lived on an upper floor of the building.
The Nordbahnhof was much damaged by allied bombing at the end of the war and demolished in 1965, though the tracks are still used for local traffic
Known today as Nordbahnstrasse 50, the former hotel seems to have escaped bombing, though the floors inside did have to be replaced about 15 years ago. This apartment block is one of those that today occupy the area of the former station:

One can identify prewar buildings here by the height of the ceilings. Those in our house are over 3 metres (10ft) high. The apartment building above gets eleven stories in the former space of five. When houses are rebuilt, as was necessitated by war damage, the ceilings are also greatly lowered, even though the exterior matches the old style. One can see that in the two buildings further down the street, where five floors now take the place of four.

Also to be seen are tramlines and cables to power the trams, which are the bane of a photographer here!
