The Naval Training Center San Diego served as a basic training facility for new Navy recruits for more than 70 years, as well as hosting many specialty schools providing advanced career training for sailors. In April 1997 the base was closed and these schools were moved to Recruit Training Command, Great Lakes, Illinois. The former site of the base is now Liberty Station, a mixed-use redevelopment project that includes residential, office, retail, educational, and civic, arts and cultural districts. Liberty Station was developed by the City of San Diego and The Corky McMillin companies. It also includes a 9-hole golf course, a waterfront park and a historic district listed with the National Register of Historic Places.
