Istanbul is a major city in Turkey that straddles Europe and Asia across the Bosphorus Strait. Its Old City reflects cultural influences of the many empires that once ruled here. In the Sultanahmet district, the open-air, Roman-era Hippodrome was for centuries the site of chariot races, and Egyptian obelisks also remain. The iconic Byzantine Hagia Sophia features a soaring 6th-century dome and rare Christian mosaics.

Baku, the capital and commercial hub of Azerbaijan, is a low-lying city with coastline along the Caspian Sea. It's famed for its medieval walled old city, which contains the Palace of the Shirvanshahs, a vast royal complex, and the iconic stone Maiden Tower. Contemporary landmarks include the Zaha Hadid–designed Heydar Aliyev Center, and the Flame Towers, 3 pointed skyscrapers covered with LED screens. 

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.
