Dubai is a city and emirate in the United Arab Emirates known for luxury shopping, ultramodern architecture, and a lively nightlife scene. Burj Khalifa, an 830m-tall tower, dominates the skyscraper-filled skyline. 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.
Abu Dhabi, the capital of the United Arab Emirates, sits off the mainland on an island in the Persian (Arabian) Gulf. Its focus on oil exports and commerce is reflected by the skyline’s modern towers and shopping megacenters such as Abu Dhabi and Marina malls. Beneath white-marble domes, the vast Sheikh Zayed Grand Mosque features an immense Persian carpet, crystal chandeliers, and capacity for 41,000 worshipers.
