Dubai, the largest city in the United Arab Emirates, is home to many extremely tall modern high-rises, 108 of which stand taller than 180 metres (591 ft). The tallest building in Dubai is the Burj Khalifa, which rises 828 metres (2,717 ft) and contains 163 floors. The tower has stood as both the tallest building in the world and the tallest human-made structure of any kind in the world since its completion in January 2010. The second-tallest building in Dubai is the 425-metre (1,394 ft) Marina 101, which also stands as the world's fourth tallest residential skyscraper. The skyscrapers of Dubai are, for the most part, clustered in three different locations. The land along E 11 Road was the first to develop, followed by the Dubai Marina neighborhood and the Business Bay district.
