I really liked this when I saw it. It's down to multiple factors... The fact that the angle of shadows lines up with the angles of the building. The way that the staircase (if that's what it is) goes against all the other angles of the building. The lovely blue sky, which peeks through both the trees and a few holes in the building itself.

But after some time trying to think about what it was that kept drawing me back to this photograph, I realised it was all about those angles.

I'm just a sucker for angles.

Incidentally, this was taken on the same day - and a few minutes before - my photograph of Senate House. It seems that was a pretty productive day...
