	The VMI campus covers , 12 of which are designated as the Virginia Military Institute Historic District, a designated National Historic Landmark District. The campus is referred to as the "Post," a tradition that reflects the school's military focus and the uniformed service of its alumni. A training area of several hundred additional acres is located near the post. All cadets are housed on campus in a large five-story building, called the "barracks." The Old Barracks, which has been separately designated a National Historic Landmark, stands on the site of the old arsenal. This is the structure that received most of the damage when Union forces shelled and burned the Institute in June 1864. The new wing of the barracks ("New Barracks") was completed in 1949. The two wings surround two quadrangles connected by a sally port. All rooms open onto porch-like stoops facing one of the quadrangles. A third barracks wing was completed, with cadets moving in officially spring semester 2009. Four of the five arched entries into the barracks are named for George Washington, Thomas "Stonewall" Jackson, George C. Marshall '901 and Jonathan Daniels '61. Next to the Barracks are offices and meeting areas for VMI clubs and organizations, the cadet visitors center and lounge, a snack bar, and a Follett Corporation-operated bookstore.
