I doubt I'm the only one who's come to this possible conclusion, but does anyone else think the CoW may have been at one time a Falmer building? The architecture is like nothing we've seen of other races. Further, to bolster my suspicions, look at the http://images.uesp.net/e/e4/SR-place-College_of_Winterhold.jpg and http://images.uesp.net/b/b1/SR-place-Auriel%27s_Chapel.jpg, While not being 100% spitting images, their structure work and materials in its design.
Does anyone else feel this could possibly be the last Falmer structure in Skyrim?
