Old Exchange and Provost Dungeon

Built in 1771 as the Customs House and Exchange, this is the last public building built by the British and is packed with historically significant highlights: patriot soldiers were held in the dungeons, George Washington was entertained here, South Carolina ratified the US Constitution here, and a portion of the original fortification of the walled city, the oldest surviving structure in Charleston, was excavated from thedungeon below in 1965. The building sits on the site where pirates were once held. Guided tours of the dungeon every 30 minutes by costumed guides and a self-guided tour of the top two floors are included.
