Unique, Historic, Timeless, Immaculate, Functional...those are just some of the words that come to mind when I think about the Cathedral of Learning. From the hollowed interior to the 41 (and counting) National Rooms there is a ton to see here and at only $3 a person (really, you could just have one person go rent the box and everyone just tag along) it is an absolute bargain.
There is a reason this place is on the National Register of Historic Places - go see why.
