Istanbul, located in both Europe and Asia, is the largest city in Turkey and one of the most populous cities in Europe. It has been the capital of three empires - Roman, Byzantine, and Ottoman - and is a cultural melting pot where East meets West. The Hagia Sophia, Blue Mosque, and Topkapi Palace are some of the city's historical landmarks.
Turkish is the official language, but English is widely spoken. Istanbul is home to a diverse population, including Turks, Kurds, Armenians, and Greeks.
