Which site was the heritage designation of Exchange and Provost in early 1980s?
Exchange and Provost The Old Exchange & Provost Dungeon , also known as the Custom House , and The Exchange , is a historic building at East Bay and Broad Streets in Charleston , South Carolina , USA . Built in 1767–1771 , it has served a variety of civic institutional functions , including notably as a prisoner of war facility operated by British forces during the American Revolutionary War . The building was designated a National Historic Landmark in 1973 . It is now a museum operated by the Daughters of the American Revolution . Description . The Old Exchange is located on the east side of Charlestons historic downtown area , at the northeast corner of East Bay and Broad Streets . It is a two-story masonry building , capped by a hipped roof with cupola and set on a high brick basement . The main facade faces west , and has a projecting three-bay gabled section at its center with entrances recessed in three round-arch openings on the first floor , and sash windows set in bays articulated by Ionic pilasters on the second . The flanking walls each have a Palladian window set on a brick base with balustrade . History . The Exchange was built from 1767–1771 by South Carolinas provincial government , and was used during the 18th century for a variety of civic functions , including as a custom house , public market , public meeting place , and jail . During the American Revolution , confiscated tea was stored here in 1774 , and it is where South Carolinas revolutionary leadership councils were held . After the British captured the city in 1780 , it was used as a barracks , and its basement was used as a military prison . In 2012 , a study was completed of the buildings use as a British prison during the Revolutionary War . Soon after taking control of Charleston in 1780 , the British started housing prisoners in the Exchange , but not exclusively in the dungeon . The investigation was able to document at least 120 prisoners held in the Exchange , but there were many more whose identities could not be discovered . The facility was not exclusively used for Colonial prisoners , and at least some British soldiers were held there too . The building housed the South Carolina convention to ratify the United States Constitution in 1788 , and was the site of many of the events in George Washingtons week-long stay in Charleston . He was greeted by a crowd on the balcony . The building continued as an Exchange until the 19th century , when it also became a post office . During the 19th century , the postmaster defended the Exchanges shipment of abolitionist pamphlets from angry Charlestonian rioters . In the American Civil War , the building remained a Confederate post office , but was hit by several shells during the war , and thus abandoned . In 1913 , the building was granted to the Daughters of the American Revolution , who have preserved it ever since . In World War I , the building served as the army headquarters of General Leonard Wood and the United States Lighthouse Service—the latter having been in the building since the late 1800s . In World War II , the building not only served as a USO facility and canteen for troops , but served as the Coastal Picket Station for the Sixth Naval District of the United States Coast Guard . In 1965 , the Half-Moon Battery , a 1698 fortification , was discovered underneath the building . The buildings first cupola was damaged by a hurricane in the early 1800s . The second deteriorated before the great earthquake of 1886 , and the third was not placed until 1981 when the building opened as a museum . The building is owned by the South Carolina Society of the Daughters of the American Revolution , who operate guided costumed tours that include all three floors of the building . The Provost Dungeon once had animatronic figures that tell stories of pirates and colonial days , but these animatronics have been supplanted by personal dungeon tours by docents .
