San Diego State University started out as a teacher training school in the late 1800s. It enrolled mostly women. The building remains intact today at its original location in downtown San Diego. It remained there for a brief period of time before moving to a location in City Heights, a magnificent building designed by Irving Gills. After outgrowing the location on El Cajon Boulevard, the school would move to its final location in the College area. Find out how the university evolved through the past century.
