The Oakland Coliseum was completed in 1966 as a multipurpose stadium. Its primary tenants were the NFL’s Oakland Raiders (now Las Vegas Raiders), but the city was hoping to attract a big-league baseball team since the Pacific Coast League’s Oakland Oaks had departed a dozen years earlier. Oakland Athletics moved to Oakland from Kansas City in 1967 and played their first game at the Oakland Coliseum on April 17th, 1968. The stadium was hailed as a Brutalist gem that could house two sports in an elegantly simple, circular design.
The Coliseum has undergone several renovations, including one in 1995-1996 and another in 2017.
