The University of Phoenix Stadium was opened in 2006 as the home of the Arizona Cardinals of the National Football League and the annual Fiesta Bowl.
The project is located in Glendale, Arizona and was designed by the practice of Eisenman Architects in collaboration with Popoulous (HOK Sport) with 63400 seats being voted one of the 10 most impressive sports facilities in the world by the Business Week due to its retractable roof and roll in natural grass field.
The construction cost was quite high reaching 518 million dollars and a part of the sum was paid by the University of Phoenix which acquired the naming rights changing it from Cardinals Stadium. The multipurpose football stadium has the first fully retractable natural grass playing surface in US and on the top it features an AirField Systems drainage system.
Since its opening the stadium featured a lot of events, hosting the Super Bowl XLII, the 2011 BCS National Championship Game, the WWE WrestleMania XXVI and it will also host the 2015 Super Bowl XLIX.
