The Walter Camp Athletic Center is named after alumnus Walter Camp, who is credited with inventing American football and later was Yale's football coach. The Athletic Center was opened in 1986 and has two floors of gyms (three basketball courts on the first floor, and weight-lifting rooms on the second), a pool, a trainers' office, and coaches' office. The first floor is largely made up of three standard-sized basketball courts and the Bud Erich Pool. The second floor includes smaller weight rooms and training areas, including the wrestling room.
