Ah! :idea: This is the STATION building! Now I see! I know I have been inside that dome, but entered from the side, is that possible? I never saw (nor went to) neither this front nor the back, I think... so I could not have seen those lovely tiles on the back.
I am amazed how sharp this photo is. What lens gave you this result? I like that this one has people in it. And I like the deep blue of the "Canary Wharf Station" sign and the fact that I can read (!) the letters!!! Very sharp!
