Istanbul

Istanbul is the only city in the world that straddles two continents, and that geographic distinction mirrors its cultural richness. Byzantine churches, Ottoman mosques, and modern galleries coexist across its hilly landscape. The Hagia Sophia, a cathedral turned mosque turned museum turned mosque again, encapsulates the city's layered history in a single building.

The food is a highlight in itself, fresh fish sandwiches from boats bobbing on the Golden Horn, simit vendors on every corner, and elaborate meze spreads in meyhane taverns. The Grand Bazaar and Spice Market overflow with color, scent, and the energy of centuries of trade. A cup of Turkish tea on a rooftop terrace overlooking the Bosphorus is one of travel's great simple pleasures.
