Turkey extends geographically over two continents. Anatolia, the Asian part of Turkey, covers about 97% of the territory. The European part in the northwest (eastern Thrace) covers about 3% of the area in which the main part of the metropolis Istanbul is located.
With a coastline of about 7,200 km in length, Turkey borders the Aegean Sea to the west, the Mediterranean Sea to the south and the Black Sea to the north. The Sea of Marmara lies between the Aegean Sea and the Black Sea and is connected to each of them by a strait: in the west the approximately 65 km long Dardanelles, in the east the Bosporus. Istanbul, the metropolis of millions, is located on the Bosporus.
The land border to the eight neighbouring countries has a total length of 2,648 km. Turkey borders Greece (206 km border) and Bulgaria (240 km) to the north-west, Georgia (252 km), Armenia (268 km), Azerbaijan (exclave and autonomous republic of Nakhichevan, 17 km) to the north-east, Iran (499 km) to the east, Iraq (331 km) and Syria (822 km) to the south.9] The politically divided island of Cyprus with the Republic of Cyprus and the internationally unrecognised Turkish Republic of Northern Cyprus is about 70 kilometres from the south coast. The Greek islands of Chios, Kos, Symi and Rhodes are also not far from the Turkish mainland.
