Drayton Hall, built in 1738, is the oldest preserved plantation house America that is open to the public. Drayton Hall is recognized for its beautiful architecture, and once played a role in the American Revolution.

The Powder Magazine is the oldest building in South Carolina (built in 1713), and served as an arsenal before and during the American Revolution. Enjoy military artifacts, interpreters in period dress and living history programming on Saturday.

The Old Exchange & Provost Dungeon is considered to be one of the three most historically significant Colonial buildings in the US. This building is linked to the Constitution, George Washington and the American Revolution.
