The Dardanelles Strait, a vital transportation bridge between the Black Sea and Mediterranean Sea, is a narrow channel of water that connects the Aegean Sea to the Sea of Marmara.
It separates Asian Turkey from European Turkey (Trace), thus it also separates the two continents.
Over the centuries this strategic strait was blockaded, crossed by invading armies in their quest for land and riches, and the site of important naval conflicts.
Russia's attempt in the early 19th century to control commerce from the Black Sea on through to the Mediterranean via the strait, forced Austria, France, the United Kingdom and others to pressure Russia to capitulate, eventually ending in Russia's defeat in the Crimean War.
Near its southern shore stands the remains of the ancient city of Troy, site of the legendary Trojan War.
