Old Las Vegas Mormon Fort State Historic Park is the birthplace of modern Las Vegas, located at 500 E Washington Ave at the southeast corner of Las Vegas Boulevard and Washington Avenue in the Downtown Cultural Corridor of Las Vegas, Nevada. Built in 1855 by missionary settlers from the Church of Jesus Christ of Latter-day Saints alongside a natural spring-fed creek, this 150-foot-square adobe fortification was the first permanent non-native structure in the Las Vegas Valley. Managed as a Nevada State Park since 1991, the site preserves the original 1855 adobe remnant—the oldest standing building in Nevada—alongside reconstructed fort walls, pioneer wagons, and a modern visitor center interpreting Southern Paiute heritage, 19th-century ranching, and the railroad boom that launched the city in 1905.
What to Expect at Old Las Vegas Mormon Fort State Historic Park
Visits begin inside the climate-controlled Old Las Vegas Mormon Fort Visitor Center, where chronological gallery displays trace how the spring-fed Las Vegas Creek created the valley’s original meadowlands—las vegas in Spanish—along the Old Spanish Trail. Artifacts, historic photographs, and dioramas detail the Southern Paiute bands who farmed and hunted here for centuries, the 30 Mormon missionaries led by William Bringhurst who arrived from Salt Lake City in June 1855 to establish a supply outpost between Utah and San Bernardino, and the subsequent ranching era under Octavius Decatur Gass and Helen J. Stewart, the “First Lady of Las Vegas.” Before stepping outdoors, guests can watch a concise orientation film and pick up a self-guided walking tour map.
Outside the visitor center, paved pathways wind into the reconstructed three-acre fort compound and shaded picnic grounds. Half of the original two-story northeast corner bastion and three reconstructed adobe walls demonstrate traditional sun-dried mud-brick construction, while a recreated version of the Las Vegas Creek flows along the perimeter to show how early settlers diverted water to irrigate orchards and grain fields. Inside the historic 1855 adobe structure, period furnishings and Bureau of Reclamation concrete-testing instruments from the 1929 Hoover Dam construction era illustrate the building’s multi-decade survival.
- Original 1855 Adobe Building: The only remaining section of the original 1855 fort walls, recognized on the National Register of Historic Places as the oldest standing building in Nevada.
- Reconstructed Fort Courtyard & Bastion: A full-scale partial reconstruction of the 14-foot-high adobe enclosure, complete with wooden gates, a two-story corner guard tower, covered pioneer wagons, and historic blacksmithing and farming tools.
- Recreated Las Vegas Creek & Orchard: A flowing water channel landscaped with fruit trees, cottonwoods, and native desert flora that replicates the original spring-fed irrigation ditch built by 1855 settlers.
- Helen J. Stewart & Gass Ranching Exhibits: Indoor museum galleries examining how Octavius Gass turned the abandoned fort into the 640-acre Las Vegas Ranch in 1865 and how Helen J. Stewart later sold the land and water rights to the San Pedro, Los Angeles and Salt Lake Railroad in 1902.
- Hoover Dam Concrete Testing Lab History: Displays inside the historic adobe room explaining how the U.S. Bureau of Reclamation leased the structure in 1929 as the first materials testing laboratory for Hoover Dam.

No advance reservations are required for individual visitors; admission is paid directly at the visitor center desk upon arrival. Travelers driving from the Las Vegas Strip or Fremont Street can enter the free surface parking lot directly off East Washington Avenue just east of Las Vegas Boulevard. Those using public transit can ride the RTC Deuce bus north along Las Vegas Boulevard to the Washington Avenue stop, situated steps from the park entrance. The entire visitor center, restrooms, shaded picnic tables, and outdoor courtyard pathways are step-free and wheelchair and stroller accessible.
Old Las Vegas Mormon Fort anchors the city’s Cultural Corridor, making it effortless to pair with neighboring attractions within a five-to-fifteen-minute walk. Directly across Washington Avenue stands The Neon Museum (770 Las Vegas Blvd N), where retired casino signs from the mid-20th century are preserved in the outdoor Neon Boneyard. Immediately north of the fort at 900 Las Vegas Blvd N sits the Natural History Museum, while a 15-minute walk south down Las Vegas Boulevard brings you to The Mob Museum and the pedestrian canopy of the Fremont Street Experience.
