McKeon Pavilion

McKeon Pavilion is a 3,500 seat multi-purpose arena at St. Mary's College of California in Moraga, California. Home men's and women's basketball and volleyball games are held in the gymnasium, the team nickname being the Gaels. Many athletic camps for youths also use the gym, primarily in the summer, and other on-campus events, such as the Baccalareate mass, are also held there. Banners commemorating successful seasons, championships and post-season appearances for all St. Mary's sports hang on the back wall. At well-attended games, the court-level bleachers opposite the benches are reserved entirely for students.

Common criticism of the gym, including by students, is its age and size. It is one of the smaller gyms in the WCC and thus cannot host the WCC Tournament. The seating is mainly along two sides, running along the long sides of the court. Behind one basket is a large wall, and behind another a handful of elevated, VIP seats. Seating is bleacher-style, not stadium style. However, many feel that the small size of the gym adds to the intensity of the crowd at sold-out games, when the cheers of 3,500 fans are amplified due to the small space. While there has been talk of renovating or even replacing the gym, there is little funding for the project and most agree that any changes are still many years into the future.

In recent memory, the gym has seen the 2001 women's basketball team and the 2005 men's basketball team reach the NCAA Tournament. The women's volleyball team has also achieved much success, reaching the post-season in 2004-2006. In January 8, 2005, the men's basketball team defeated West Coast Conference powerhouse Gonzaga University 89-81 in McKeon, ending a 17-game losing streak against the Zags and handing Gonzaga its first WCC loss in 17 games.

It opened January 21st, 1978. It is the largest enclosed arena in Contra Costa County.
