Italy
A Masonic Temple, the headquarters of the Scottish Rite, and a prominently featured location in Dan Brown's 2009 novel, ''The Lost Symbol''. It's almost absurdly grand, pretty easily outshining the similar Supreme Court Building in Capitol Hill, and there's nary a Washingtonian around who hasn't at
some point walked by it, surprised by this enormous but unidentified building. The interior is a wild Orientalist fantasy in way that only the Masons could bring to life, and is open to the public for tours and exhibits.
