The Fremont Street Experience (FSE) is a pedestrian mall and attraction in downtown Las Vegas, Nevada. The FSE occupies the westernmost five blocks of Fremont Street, including the area known for years as "Glitter Gulch," and portions of some other adjacent streets. The central attraction is a barrel vault canopy, 90 ft (27 m) high at the peak and four blocks, or approximately 1,500 ft (460 m), in length. While Las Vegas is known for never turning the outside casino lights off, each show begins by turning off the lights on all of the buildings, including the casinos, under the canopy. Before each show, one bidirectional street that crosses the Experience is blocked off for safety reasons. Concerts, usually free, are also held on three stages. The venue has become a major tourist attraction for downtown Las Vegas, and is also the location of the SlotZilla zip line attraction and the city's annual New Year's Eve party, complete with fireworks on the display screen.
