Rockville, one of Charleston County’s oldest surviving summer resorts (ca. 1824), is important architecturally, agriculturally, militarily and in the areas of transportation and recreation. This summer community’s serene, slow-moving, lifestyle is reflected in its architecture and landscape. Although houses vary in size and degree of architectural importance, nearly all have spacious porches, raised foundations, and large central hallways designed for summer comfort and relaxation. The buildings within Rockville’s Historic District have obvious visual unity. All are well ventilated to take full advantage of sea breezes. Several houses appear to have been year-round residences with architecture adapted for cold weather but still well-ventilated for summer use. The district also includes two churches. Live oaks draped with Spanish moss and palmettos dominate the landscape and add to the quaint atmosphere of the community. Listed in the National Register June 13, 1972.
