rural retreat of U.S. presidents in Catoctin Mountain Park, a unit of the National Park Service on a spur of the Blue Ridge Mountains (Blue Ridge) in Frederick county, northern Maryland, U.S. Camp David lies just west of Thurmont and 64 miles (103 km) northwest of Washington, D.C. (Washington) The retreat, which comprises a scenic mountainous area of 200 acres (81 hectares), is surrounded by maximum-security fencing and is closed to the public. It was established as Shangri-La in 1942 by President Franklin D. Roosevelt (Roosevelt, Franklin D.), who named it for the Tibetan paradise in James Hilton's novel Lost Horizon. President Harry S. Truman (Truman, Harry S.) made it the official presidential retreat in 1945, and President Dwight D. Eisenhower (Eisenhower, Dwight D.) renamed it Camp David in 1953 for his grandson. The retreat is administered by the White House Military Office and includes a presidential office and living quarters, swimming pool, and meeting hall. Since the meeting there during World War II between President Roosevelt and British Prime Minister Winston Churchill, it has been the scene of a number of high-level presidential conferences with foreign heads of state. In September 1978, through the intervention of President Jimmy Carter (Carter, Jimmy), the retreat was the site of a historic peace agreement (known as the Camp David Accords) reached between Egyptian President Anwar el-Sādāt (Sādāt, Anwar el-) and Israeli Prime Minister Menachem Begin (Begin, Menachem).
