New Orleans Saints
History: The Superdome, opened in August 1975, is the largest indoor facility in the country for football and with its 20,000 tons of structural steel is the biggest steel-constructed venue. Besides its sheer enormity it might not be much to look at, but, remember, you're only a mile from the French Quarter. The Saints Hall of Fame, honors the team with busts and paintings of the 33 inductees, exhibits, memorabilia and videos. The hall really is quite impressive, especially considering the team has never reached the Super Bowl. Close to $140 million was spent to repair damages to the Superdome suffered in August 2005 during Hurricane Katrina; nearly 30,000 people reportedly took refuge in the building following the hurricane.
