The city abounds in great museums, which house everything from the archaeological wonders of ancient Turkey, to the finest Chinese and Iznik porcelain, jewels and decorative arts.
This explains why Istanbul is overwhelmingly rich in art and architecture. The Hagia Sophia is one of the great architectural achievements of mankind, and the great Ottoman mosques are among the finest Islamic buildings in the world.
Sultans replaced Roman emperors and churches became mosques.
In 1453 the city of Constantine became ‘Istanbul’ after it fell to the Ottoman Turks.
Istanbul is unique in sitting astride two continents.
