One of three buildings in Cambridge designed by Christopher Wren (the others being the Wren Libraryof Trinity College and the chapel in Pembroke) Emmanuel College's chapel is quite gorgeous. Built 1668-74, it has a symmetry and grace that speak for themselves although it's not quite as spectacular as the library. See the whole facade here. For once I 'm not sure the angle does it justice but I don't have a straight shot so I'll point you to this one. Either way, the building's stunning.
