An Underground Prison Among the Antebellum Mansions
One of the most important buildings used during the American Revolution is the Old Exchange and Provost Dungeon. Upper floors house period antiques and dress. American patriots were held in the dank dungeon that is a marvel in design. The impressive structural arches have withstood all kinds of damaging weather. Guides in period costume do an excellent job of re-creating the era. Recent excavations have revealed pieces of the original 18th-century wall of the Charleston Harbor.
