Though the Hilton, originally the International, is now one of the more mundane-looking casinos near the Strip, in 1969 it marked a break with the casinos of the 1950s and early 1960s. Martin J. Stern, Jr., an architect based in Beverly Hills, designed numerous hotels and casinos in Nevada, most of them in Las Vegas. The building was the largest three-wing tower constructed in the city at that time; yet only four years later, in 1973, it gained a 1,500-room wing, doubling its capacity. The hotel's curved sides add some interest to the otherwise monotonous rows of windows. Built just off the Strip on Paradise Road, the Hilton, lacking the highway as a focus, stands as a self-contained monument, unrelated to the earlier buildings surrounding it. Though constructed for an independent entrepreneur, Kirk Kerkorian, the hotel represented the move toward a corporate style in Las Vegas that left its mark on all casinos built in the 1970s. This style, characterized by massive, boxy towers, looked more to office building architecture than to the unique resort environment of Las Vegas.
