The first permanent non-native settlers in the Las Vegas Valley were a group of Mormon missionaries who built an adobe fort along Las Vegas Creek in 1855. The fort was called Old Las Vegas Mormon Fort. They successfully farmed the area by diverting water from the creek. Today, the park includes a remnant of the original adobe fort, which contains interpretive displays. The Visitor Center contains exhibits on the history of the site, as well as historic artifacts. Historic interpretation is and will remain the focus of the park. The Old Las Vegas Mormon Fort is located in downtown Las Vegas, at the intersection of Las Vegas Boulevard and Washington Avenue. The Park and Visitor Center are open from 8:00 a.m.-4:30 p.m., Tuesday through Saturday, year round.
