The stadium had a fiberglass fabric roof that was self-supported by air pressure and was the third major sports facility to have this feature (the first two being the Pontiac Silverdome and the Carrier Dome). The Metrodome was similar in design to the former RCA Dome and to BC Place, though BC Place was reconfigured with a retractable roof in 2010. The Metrodome was reputedly the inspiration for the Tokyo Dome in Tokyo, Japan. The stadium was the only facility to have hosted a Super Bowl (1992), World Series (1987, 1991), MLB All-Star Game (1985) and NCAA Division I Basketball Final Four (1992, 2001).
