İstanbul, Turkey

State guide with cities, regions, and key information.

Introduction
İstanbul Province spans both the European and Asian sides of the Bosphorus Strait, making it the only province in the world that straddles two continents. Home to 16 million people in Turkey's largest city, the province concentrates the country's economic, cultural, and historical weight — from Byzantine and Ottoman monuments in the historic peninsula to modern business districts, island escapes, and Black Sea coast forests.

Hagia Sophia, Blue Mosque, Topkapı Palace, Basilica Cistern, Grand Bazaar, and Spice Bazaar. The UNESCO-listed historic core concentrates 2,500 years of architecture. Sultanahmet is the tourist epicenter; Fatih and Balat offer local Istanbul beyond the monuments.
