The University of Pittsburgh's Cathedral of Learning is the highest academic building in the United States at (I believe) 37 stories. There's an incredible view from the top of downtown Pittsburgh.
Also, on the first floor, there are classrooms called the Nationality Rooms. Each room is decorated in the architectural style of the country it's named after.
AEPhi Alum: That building is so cool looking! What is housed there?
Munchkin: I can't remember what it housed, but I remember a building across Amsterdam from the main part of campus and connected by a footbridge that always reminded me of a gigantic toaster oven! I *think* it might have been the Law School, but it was long ago so don't quote me on it
