The Rice Museum, known locally as The Town Clock, is located in the Old Market Building and is a prominent symbol of Georgetown County. Through dioramas, maps, artifacts and other exhibits, visitors to the Museum are enlightened to the history of a society dependent on the rice crop. In 1750, George Town became the center of rice production in the colony. By 1840, the Georgetown District (later County) produced nearly one-half of the total rice crop of the United States. The 1850s proved to be the most profitable decade for the rice planters. The Rice Museum chronicles this most important American timeline and its impact on not only South Carolina, but internationally as well.
