Camp David is a 125-acre (51 ha) country retreat for the president of the United States. It is located in the wooded hills of Catoctin Mountain Park, in Frederick County, Maryland, near the towns of Thurmont and Emmitsburg, about 62 miles (100 km) north-northwest of the national capital city of Washington, D.C. It is code named Naval Support Facility Thurmont. Technically a military installation, its staffing is primarily provided by the Seabees, Civil Engineer Corps (CEC), the United States Navy and the United States Marine Corps. Naval construction battalions are tasked with Camp David construction and send detachments as needed.
Originally known as Hi-Catoctin, Camp David was built as a retreat for federal government agents and their families by the Works Progress Administration. Construction started in 1935 and was completed in 1938. In 1942, President Franklin D. Roosevelt converted it to a presidential retreat and renamed it "Shangri-La", after the fictional Himalayan paradise. Camp David received its present name in 1953 from President Dwight D. Eisenhower, in honor of his father and his grandson, both named David.The Catoctin Mountain Park does not indicate the location of Camp David on park maps due to privacy and security concerns, although it can be seen through the use of publicly accessible satellite images.
