Istanbul is the only city established on two continents at the location where the continents of Asia and Europe are divided by a narrow sea strait, "Bosphorus", extending to Asia with its one arm and to Europe with the other. The city of Istanbul is on a peninsula surrounded by the Sea of Marmara, the Bosphorus and the Golden Horn on three sides. The city has served in order as a capital to the Roman, Byzantine and Ottoman Empires, with 120 emperors and sultans ruling here for approximately 1,600 years.
The history of Istanbul goes back to 300 thousand years ago. The first traces of human culture were discovered in the excavations carried out in Yarımburgaz Cave on the banks of Küçükçekmece Lake. It is estimated that starting from 5,000 B.C., a concentrated settlement activity started in Çatalca, Dudullu, Ümraniye, Pendik, Davutpaşa, Kilyos and Ambarlı, led by Kadıköy Fikirtepe. The foundations of today's Istanbul were laid in 7th Century B.C. The city was reconstructed and made capital by Emperor Constantin in 4th Century B.C., maintaining its title of the capital for approximately 16 centuries thereafter. After it was captured by the Ottomans in 1453; its name, which was Constantinople was changed to Istanbul by Sultan Mehmet, the Conqueror; starting to be deemed as one of the most important cities of Muslims. 50 years after the conquer, Istanbul was the biggest city in Europe.
Entering the 16th Century as a big city, Istanbul was damaged greatly in 1509 earthquake with thousands of buildings coming down in the earthquake which lasted 45 days. In 1510, it was almost rebuilt when Sultan Bayezıd II employed 80,000 people to do this. Hence, a great majority of works, which survived until today, have remained from this period.
