porthole

This is fantastic. The books, the chairs, the floor, THE DOOR. I am calling this a Porthole Door because I cannot find anything with a real name (although I now know that all pressure vessels have round or oval doors. wooooo thank you internet). I don't know what would possess someone to put a door like this in their library, but I want a shot of it because it is awesome.
