The Dragons might be smart, but why would they have known about architecture. As I explained the white like rock substance that made the Castle Volkihar floor is nothing like anything else in Skyrim at the time. Who would've built a caslte in Northern Skyrim, at the beginning of the First Era? I'm not completely sure they made it, but based on logic and common sense.
