Dubai is one of the seven emirates that make up the United Arab Emirates. It has experienced rapid growth from a small fishing and pearl diving village to a modern metropolis due to its oil discovery in 1966 and development of tourism and real estate. Some of Dubai's most notable landmarks include Burj Khalifa, the tallest building in the world, and the Palm Islands residential and resort developments. Dubai has positioned itself as a business and tourism hub through tax-free zones and its vision to be one of the most visited cities, with future projects continuing its ambitious expansion plans.
