El Cortez Hotel & Casino (historic downtown casino, opened 1941)

El Cortez opened in 1941 at its downtown location and is one of Las Vegas's oldest continuously operating casinos. The property retains historic features from its early years, including original-style neon signage and classic interior elements. Some sources describe El Cortez as the city's longest-running casino, though claims about the absolute 'oldest' casino in Las Vegas are sometimes debated among local historians.
