Guess Where Tube 10 - Gate?

Continuing the series where I ask you to try to guess from exactly where on the London Underground, the following picture in the London Tube Flickr group was taken from.


I was obviously too easy with the last one - Guess Where Tube 9 as I felt sad that only one of you guessed the exact specfic location of Guess Where Tube 8.

Now, no mercy, this week's is really hard again. I need you to give the exact location of where I took this picture of one of the Art on The Underground series of posters - A Lock is A Gate. And try not to look at the comments in front of you before making your guess.

Yet again, there's no prizes for getting it right, just the satisfaction of knowing you were right.

Enjoy!
