10. University of Phoenix Stadium

(Arizona Cardinals)

Opened: 2006

Capacity: 63,400

Few stadiums have the technological advancements of the home of the Cardinals. The entire playing field can slide through an opening outside of the building in order to expose the natural surface to direct sunlight. The unique metallic exterior and massive retractable roof make this one of the most well respected and unique stadiums among engineers worldwide. The $455 million building has hosted a Super Bowl and the Fiesta Bowl among other big events since opening.
