Round Church, originally uploaded by Neorelix.

Yeah, and I'm to be the dashing-and-windswept-though-slightly-befuddled hero... mmm, quite. Ok, so neither claim is true but this was allegedly built by the Knights Templar in 1130. It's the Church of the Holy Sepulchre here in Cambridge (facing St. John's College) and is one of only four mediaeval round churches left in England. They're likely modelled on the church of the same name in Jerusalem. Of course, locals just call it The Round Church. There's a good deal of information and some nice shots of the interior onthis page. BTW, that's two in a row on the level and it hurts...
