Dubai is the capital of an emirate of the same name which is part of the United Arab Emirates. It’s Burj Khalifa, an 830m-tall tower, dominates the skyscraper-filled skyline. It is a global city and business hub of the Middle East. At its foot lies Dubai Fountain, with jets and lights choreographed to music. On artificial islands just offshore is Atlantis, The Palm, a resort with water and marine-animal parks.
