Smithsonian Castle haunting legends

The Smithsonian Institution Building ('The Castle') on the National Mall is the subject of long-standing local ghost stories and reports of unexplained occurrences. These tales are part of Washington folklore and are commonly mentioned in popular ghost tours, but the Smithsonian and historians note there is no documented, verifiable evidence of paranormal activity. The Castle was completed in 1855 and currently houses Smithsonian administrative offices and visitor information.
