Old Las Vegas Mormon Fort State Historic Park is a state park of Nevada, containing the Old Mormon Fort, the first structure built by people of European heritage in what would become Las Vegas fifty years later. In present-day Las Vegas, the site is at the southeast corner of Las Vegas Boulevard and Washington Avenue, less than one mile north of the downtown area and Fremont Street. This is the only U.S. state park located in a city that houses the first building ever built in that city. The fort was listed on the National Register of Historic Places on February 1, 1972. The site is memorialized with a tablet erected by the Church of Jesus Christ of Latter-day Saints in 1997, along with Nevada Historical Marker #35, and two markers placed by the Daughters of Utah Pioneers.
