Louisiana Superdome The Louisiana Superdome, often informally referred to simply as the Superdome, The Dome or the New Orleans Superdome is a large, multi-purpose sports and exhibition facility located in the Central Business District of New Orleans, Louisiana. It was designed in 1967 by the New Orleans modernist architectural firm of Curtis and Davis, which also designed the main branch of the New Orleans Public Library (1956-58). The Superdome is primarily home to the NFL's New Orleans Saints and the Sugar Bowl college football game. It is also one of the few facilities in the United States which can adequately host major sporting events such as the Super Bowl and the Final Four; as such, given New Orleans popularity as a tourist destination, whenever the Superdome bids to host such an event it routinely makes the "short list" of candidates being considered. The Superdome is the largest fixed domed structure in the world. Its structural steel frame covers a 13-acre (53,000 m2) expanse. Its 273-foot (83 m) tall dome is made of a Lamella multi-ringed frame and has a diameter of 680 feet (210 m). In 2005, the Superdome came to international attention when it housed thousands of people seeking shelter from Hurricane Katrina, and was damaged in the storm.
