Istanbul is a city built on layers of empire. Spanning two continents, it was once the capital of three major empires: Roman, Byzantine, and Ottoman. Visitors walking through the Sultanahmet district can witness this timeline firsthand, from the Roman-era Hippodrome to the Byzantine mosaics of Hagia Sophia, and the towering minarets of the Blue Mosque. At nearby Topkapi Palace, rooms still display the jeweled swords, ceremonial robes, and handwritten Qurans once used by Ottoman sultans.

The Chobe River forms the northern boundary of the Chobe National Park.
