Old Las Vegas Mormon Fort, Pioneer fort in Downtown Las Vegas, United States.

The Old Las Vegas Mormon Fort is a tan-brown adobe structure. A tall square tower with a flat roof of wooden beams projecting over the walls stands at the left and center; the beams rest on rounded wooden corbels. The tower has one small square window on its upper left face and one narrow vertical opening on its upper right face. To its right is a lower brick wall topped by a horizontal wooden beam on upright posts, and a dark doorway opens into the tower's base.

Missionaries built the fortification in 1855 near Las Vegas Springs to create a supply station on the route to California. After a few years they left the compound, which was later used by ranchers and other settlers.

The site preserves building methods from early southwestern frontier settlers and displays tools and everyday objects from that era. Visitors can follow how the first residents organized their rooms and lived with the local springs.

The site sits at the southeast corner of Las Vegas Boulevard and Washington Avenue, under a mile north of Fremont Street and downtown. A visitor center completed in 2005 explains the fort's history and holds the entrance. Look for Nevada Historical Marker #35 and the 1997 Latter-day Saints tablet on the grounds.

The springs on site supplied travelers heading to the Pacific coast with water for decades, even before the city itself arose. Today the fort is one of the few remaining examples of adobe construction from the mid-19th century in Nevada.
