The Alamodome is a domed 65,000-seat, multi-purpose facility used as a football, basketball, baseball stadium and convention center. It is located on the southeastern fringe of Downtown San Antonio, Texas, USA. The facility opened on May 15, 1993, having been constructed at a cost of $186 million.
The multi-purpose facility was intended to increase the city's convention traffic and attract a professional football franchise. It also placated the San Antonio Spurs' demands for a larger arena. The Spurs played in the Alamodome for a decade, then became disenchanted with the facility and convinced Bexar County to construct a new arena for them, now called the AT&T Center.(Wikipedia)
