Wall Aquatic Center

Northern Arizona University constructed the Natatorium - Latin for "swimming place" - in 1983 for $5 million. It boasted a fifty-meter pool, two three-meter lanes, two one-meter diving boards, and a shallow lounging area. The bleachers accommodated 350 spectators.

In 1996, NAU renamed it the Wall Aquatic Center (WAC) after Douglas J. Wall, an attorney to the University who helped obtain funding for its construction.

American Olympic gold medalist athletes, including Gary Hall, Jr., Anthony Ervin, and Dana Vollmer all used the facility. Training at Flagstaff's high altitude forces athletes' bodies to transport oxygen better, helping their endurance in anaerobic sports. After constructing the new Aquatics and Tennis Facility, the University demolished the Center in April 2016 to make way for a recreational field and tennis courts.
