Coveted by empires across the centuries, straddling both Europe and Asia, Istanbul is one of the world's great metropolises. Founded around 1000 BC, the colony of Byzantium grew into the Byzantine Empire's great capital of Constantinople and after the Ottoman conquest of the city, retained its glorious place as the heart of their empire. The city (officially renamed Istanbul after the founding of the Turkish Republic) is liberally scattered with glorious remnants of its long and illustrious history, and the sightseeing here will impress even the most monument-weary visitor.

As well as the big four (Aya Sofya, Topkapi Palace, Blue Mosque, and Grand Bazaar), leave enough time to explore the other sights. Although many tourist attractions are located in, or near, the old city district of Sultanahmet, there is a dazzling array of other things to do throughout the farther reaches of the city.
