Completed in 1771, the Old Exchange Building is a Charleston landmark and the site of some of the most important events in South Carolina history. Over the last two and a half centuries, the building has been a commercial exchange, custom house, post office, city hall, military headquarters, and museum.

The Old Exchange Building is today held in a public charitable trust by the South Carolina State Society and the Rebecca Motte Chapter of the Daughters of the American Revolution. It is governed by the Old Exchange Building Commission and managed by the City of Charleston.

The Provost Dungeon


During the American Revolution, British forces converted the bottom floor of the Exchange into a military prison known as the Provost or “dungeon.” American prisoners of war, British soldiers, private citizens, and enslaved people all endured its harsh confines.

George Washington's Southern Tour


In 1791, city leaders entertained President George Washington at the Exchange with a series of lavish dinners, concerts, and dances, attended by hundreds of members of Charleston’s elite.

The Ratification of the United States Constitution


Previously a meeting place for local Patriots, the Exchange in 1788 hosted South Carolina leaders as they debated and approved the U. S. Constitution. Today, the Old Exchange Building is one of only three structures remaining where the nation’s founding document was originally ratified.

The Domestic Slave Trade


Between the American Revolution and the Civil War, the Exchange was Charleston’s most common destination for public slave auctions, making the site one of the most important in the history of the domestic slave trade.

The Half-Moon Battery


Finished in 1701 and excavated from underneath the Old Exchange Building in 1965, the Half-Moon Battery is the only standing portion of the original Charles Town city wall that is open for public viewing.

Architecture


One of the country’s premiere examples of Georgian-Palladian design, the Exchange was constructed from the finest materials available as a symbol of colonial Charles Town’s wealth and power.

“In our society, it is accepted that we set aside homes where
great men are born, but in this house, South Carolina was born.”
