The oldest religious congregation in South Carolina., established in 1681. The current location was completed in 1723 but burned to the ground in 1835. The current building was erected in 1835 and the steeple was added between 1848 and 1850. The steeple served as the rear tower of a set of range lighthouses to guide mariners into Charleston's harbor. The church is one of only two in the United States known to have served this function. Tours are available.
