The Coors Events Center is an 11,064-seat multi-purpose arena on the Boulder main campus of the University of Colorado. It opened in 1979, and is home to the Colorado Buffaloes men's and women's basketball teams and the volleyball team. The building is an eight-sided concrete structure, with three levels. The arena floor, the service level and the concourse level. The building is single-tiered inside. It replaced the Balch Fieldhouse, the current home of the indoor track and field team located directly adjacent to Folsom Field.
