Istanbul is Europe's most populous city (the world's 4th largest city proper and 20th largest urban area) and Turkey's cultural and financial centre. The city covers 27 districts of the Istanbul province. It is located on the Bosphorus Strait, and encompasses the natural harbor known as the Golden Horn, in the northwest of the country.
Part of Istanbul’s great attraction is its unique position on two continents, divided by the Bosphorus. Most of the population live on the European side; the Asian sector is reached via the high-level Bosphorus Bridge, the Fatih Sultan Mehmet Bridge or by ferry. With 13 million inhabitants Istanbul offers all the excitement of a cosmopolitan city. Its numerous monuments, mosques and museums, plus the famous Grand Bazaar, make it one of the world’s great destinations.
