The Bosphorus strait connects it to the Black Sea and the Dardanelles strait to the Aegean Sea. The former also separates Istanbul into its Asian and European sides. The Sea of Marmara is the smallest sea in the world. It has an area of 11,350 km2 (280 km x 80 km). Its greatest depth is 1,370 m (4,490 ft).
