The Main Gate serves as the entrance to the Marine Barracks Historic District. The US Marine Corps Barracks and Commandant’s House comprise the nation’s oldest continually active Marine Corps installation. Situated in southeast Washington, the post includes the Marine Corps Commandant's House, a range of barracks, a band hall, a row of five officer’s quarters, and a modern service building. These structures form a quadrangle that encloses a rectangular parade ground. Except for the Commandant’s House, which faces north, all the buildings face the parade ground.
