Guardian Angel Cathedral is a mid-century modern Catholic cathedral located on the Las Vegas Strip, commissioned by the Bishop of Reno in 1961. Designed by architect Paul Revere Williams, the structure features a distinctive triangular A-frame shape and soaring peaked roof. The sanctuary is noted for its extensive use of vibrant mosaics and stained glass, including a notable mural depicting the history of the region. Originally serving as a chapel for tourists and casino workers, it was designated as the Cathedral for the Diocese of Las Vegas in 1995. The building stands in stark visual contrast to the surrounding glass and steel casino resorts. It remains an active parish church offering regular liturgical services.
