Mercedes-Benz Superdome

The Mercedez-Benz Superdome is the highlight of the New Orleans skyline, with its intriguing design suggesting that an alien spaceship just landed downtown. Although public tours aren't offered, it's fun to just walk around this venue,home to the much loved Saints. With seating for more than 70,000 and no bad seat in the house, the Superdome has hosted 10 Super Bowls including Super Bowl XLVII in 2013. A dynamic litany of concerts, expos and festivals are hosted here, with tickets often at a premium. Located in the heart of the Central Business District, the Superdome is easily accessible by foot, taxi and streetcar from all the major hotels. Thanks to a $336 million redo, the arena made infamous as a hellish refuge of last resort during Katrina is now, a decade later, a promising symbol of the city's return from disaster.
