Well, there was a fairly strong consensus that the building I posted yesterday was St Pancras Hotel. However, Adam was right to stand by his conviction, and Kevin who posted on Facebook was also correct. It is indeed the Natural History Museum, that great cathedral of science deigned by Waterhouse in 1864.
The photo was taken underneath the vast Romanesque (semi-circular) arches of the main entrance.
I can see why many of you though it was St Pancras, it does have a few Romanesque arches along the wings, but its main entrance has a pointed arch and is not as deep. Its bricks are also more red than the NHM.
