Since Las Vegas was founded in 1835, fiestas have been celebrated at the Old Town Plaza, but a Fourth of July celebration did not begin until 1882.
Before then, grand celebrations were held on the Plaza for traditional Hispanic religious funciones on July 25 and 26, los días de Santiago y Santa Ana (St. James the Greater, patron saint of Spain, and St. Anne, patron saint of mothers and family). These religious feast days have been celebrated by the Hispanic community for centuries, and are still commemorated throughout New Mexico.
