Haas Pavilion (1999) is named for benefactor Walter Haas. It seats 12,000 and contains several large venues for athletic and special events. It replaced Harmon Gymnasium (1933), the site of many exciting basketball games as well as volleyball and gymnastics. Harmon's original facade is preserved and on display inside Haas Pavilion. The adjacent Spieker Aquatic Complex hosts swimming and water polo events, and is home to many nationally-ranked and Olympic athletes.
