U.S. Coast Guard Historic District, Historic district on Sullivan's Island, South Carolina, United States

The U.S. Coast Guard Historic District is a coastal rescue complex on Sullivan's Island containing three main buildings and a signal tower arranged in an L-shaped configuration. The structures date from different periods and demonstrate how rescue infrastructure evolved at this location.

The station began in 1891 as a life saving facility and expanded with additional buildings through the 1930s. This growth reflected the transition from the independent Life Saving Service to the modern Coast Guard organization.

The district's name comes from the U.S. Coast Guard, which took over the site's life-saving station in 1915. The station house, boathouse, garage and signal tower stand in an L-shaped court around a bunker/sighting station of about 1898, showing how crews watched the water and launched rescue boats from the same yard.

The district stands at the foot of the Charleston Light on Sullivan's Island, with the station house, boathouse, garage and signal tower grouped around an L-shaped court. The lighthouse itself is not part of the historic district. The buildings are best viewed from the street; the grounds are not described as a staffed museum in the sources.

Two surfmen from this station earned Silver Lifesaving Medals, with James J. Coste honored posthumously in 1898 for his service. His recognition shows how the nation acknowledged the sacrifices made by these rescue workers.
