No idea, but the floor at Fitz doesn't look like that, nor have I ever seen a room like that. Mind you, I'm just taking it on trust that the second photo is indeed Sydney Sussex. Don't think I ever went there (certainly not to the roof). I'd be surprised if there was an unrestricted view of the UL from there. Surely bits of Trinity would get in the way? Maybe this is Trinity. Still. Who cares, eh?
