Dubai is an emirate city of the United Arab Emirates known for its luxurious commerce, ultra-modern architecture and lively nightlife. Burj Khalifa, an 830m tall tower, dominates the skyscraper-filled landscape. At its feet is the Dubai Fountain, choreographed by jets and lights to the rhythm of the music. On the artificial islands just off the coast are Atlantis, La Palma, a tourist center with water and marine animal parks.
