Opened in December 1949,[7] the arena currently lists a seating capacity of 9,301[8] and is home to the Oregon State Beavers' basketball, wrestling, volleyball, and gymnastics teams.

Inside, on the south wall of Gill Coliseum is a painted mural of many former players, including Gary Payton, Brent Barry, A. C. Green, Lester Conner, and Steve Johnson.

[9] The name "Gill Coliseum" was initially an informal and unofficial moniker in honor of the team's longtime and then-current head basketball coach Amory "Slats" Gill, with Oregon State initially prohibited by the state board of higher education from naming a building after a living individual.

[13][14] The facility has a sports medicine center, located on the lower level of the coliseum, that provides injury prevention and rehabilitation services.

Prior to the 2013–14 season, the court was updated to reflect the athletic department's re-branding along with some graphics surrounding the lower seating.

[citation needed] Construction of the Sports Performance Center (SPC) began in early 2007, and work was completed in spring 2008.
