The main campus is located at 1900 North White Sands Boulevard in Alamogordo, New Mexico. Most of the old buildings on the main campus have been razed since World War II. The oldest surviving building is the original Teachers' Cottage, built in 1918 and renamed the Paul and Lois Tapia Building in 2006. Four of the campus buildings are listed in the National Register of Historical Places: the Administration Building (now the Paul and Lois Tapia Building), the Auditorium and Recreation Building (Harry Ditzler Auditorium), the Central Receiving Building, and the Infirmary Building
