The Las Vegas Strip is a stretch of Las Vegas Boulevard South in Clark County, Nevada, internationally known for its concentration of resort hotels and casinos along its route. The Strip is approximately 4.2 miles (6.8 km) in length, located immediately south of the Las Vegas city limits in the unincorporated towns of Paradise and Winchester. However, the Strip is often referred to as being "in Las Vegas". Most of the Strip has been designated an All-American Road, and is considered a scenic route at night. Many of the largest hotel, casino, and resort properties in the world are located on the Las Vegas Strip. Fifteen of the world's 25 largest hotels by room count are on the Strip, with a total of over 62,000 rooms.
One of the most visible aspects of Las Vegas' cityscape is its use of dramatic architecture. The rapidly evolving skyline and constant modernization of hotels, casinos, restaurants, residential high-rises, and entertainment offerings on the Strip, have established it as one of the most popular destinations for tourists in the United States, and the world.
