AT&T Stadium is currently the world's largest covered stadium with 80,000 seats. A pair of nearly 300 ft (91 m)-tall arches spans the length of the stadium dome, anchored to the ground at each end. The new stadium also includes "more than 3,000 Sony LCD TV's throughout the luxury suites, concourses, concession areas and more, offering fans viewing options that extend beyond the action on the field," and a center-hung video board that is the largest high-definition television screen in the world. Glass doors, allowing each end zone to be opened, were designed and built.
