An exterior view of the Riviera Hotel and marquee. The marquee is advertising "Edie Adams" "Rowan and Martin" "Starlite Lounge" "Lionel Hampton" "The Cousins" and the "Sawyer Sisters". The Riviera (colloquially, "the Riv") opened on April 20, 1955 as the first high-rise at 9 stories, and the ninth resort on the Las Vegas Strip. Liberace cut the opening ribbon, and became the first resident performer. The Riviera also broke new ground in its design: previously, Strip resorts resembled roadside motor courts. The Riviera underwent an expansion from 1988 to 1990 this included the 24 story Monaco Tower designed by Martin Stern Jr. and two parking garages. In February 2015, the Las Vegas Convention and Visitors Authority acquired the Riviera hotel and its associated land for $182.5 million. The property was leased back to its existing operators, Paragon Gaming, who officially closed the establishment on Monday, May 4, 2015. Due to its size, the Riviera was demolished through two separate implosions conducted in June and August 2016. The first implosion took place at 2:35 a.m. (Pacific Time) on June 14, 2016, taking down the 24-story Monaco tower. A firework display and countdown led up to the implosion. On August 16, 2016 at 2:30 a.m., the Monte Carlo tower along with the 12 story tower constructed in 1966 were imploded. The property was located at 2901 Las Vegas Boulevard South, Las Vegas, NV 89109.
