Istanbul

Walk between two empires in a single square — where a church that stood for a thousand years became a mosque, chariots raced for Byzantine emperors, and a forest of stolen columns guards an underground lake. Sultanahmet holds more concentrated history per square meter than anywhere on Earth.

Lose yourself in a 4,000-shop labyrinth that has been the commercial crossroads of empires since 1461. From saffron and sumac to hand-knotted carpets and hammered copper, this is where trade routes ended and bargaining became an art form.

Cross the Golden Horn to the side the Genoese merchants claimed, climb the medieval tower they built to guard their gold, then walk the avenue where European embassies, jazz clubs, and revolutionary politics shaped modern Turkey.
