Basilica 
Description
Originally built as a administrative and throne hall for emperor Constantine, the building is massive by modern standard to have no internal support, for something that's been standing for nearly 2,000 years its absolutely incredible. The ceiling is around 100 feet above floor level and is supported solely by the external walls. Today the Basilica makes for a very large church
