This is thought to be the state's only existing building that was used for slave auctioning, a practice that ended here in 1863. It was once part of a complex called Ryan's Mart, which also contained a slave jail, kitchen, and morgue. It is now a museum that shares the history of Charleston's role in the slave trade, an unpleasant story but one that is vital to understand. Charleston was a commercial center for the South's plantation economy, and slaves were the primary source of labor both within the city and on the surrounding plantations. Galleries are outfitted with interactive exhibits, including push buttons that allow you to hear voices relating stories from the age of slavery. The museum sits on one of the few remaining cobblestone streets in town.
