The stadium made its debut in baseball in 1968. It was built circular, with three decks and no roof. This very plain and drab stadium underwent a $120 million renovation in 1995 that added 22,000 new seats, 90 luxury suites, two private clubs and two state-of-the-art scoreboards. The first crowd filled the stadium on Sept. 8, 1966, when the AFL's Raiders played the Kansas City Chiefs. The A's, who had moved from Kansas City, followed suit on April 17, 1968. Also see the Pilgrimage to the coliseum.
Soak up the scene:
The A's have called this spacious park home for more than 40 years and share it with the Raiders. Tailgating is popular before games in the surrounding parking lots. For more on O.co Coliseum experience, including a game-day itinerary, visit Wise Guides.
