The city of Las Vegas, Nevada and its surrounding unincorporated communities in the Las Vegas Valley are the sites of more than 160 high-rises, 42 of which stand taller than 400 feet (122 m). The tallest structure in the city is the Stratosphere Tower, which rises 1,149 feet (350 m) just north of the Las Vegas Strip. The tower is also the tallest observation tower in the United States. Since the Stratosphere Tower is not fully habitable, however, it is not considered a building. The tallest building in Las Vegas is the Fontainebleau Resort Las Vegas, which rises 735 feet (224 m) and was topped out in early 2009. This building, however, is currently on hold.
