(Credits: Wikipedia, Marmara Island)

The Sea of Marmara is the smallest in the world. It is located entirely within Turkey, acting as a natural link between the Black Sea to the northeast and the Aegean Sea to the southwest. Its origin point can be considered the connection with the Black Sea via the Bosporus Strait, which flows into the Sea of Marmara, and from there it continues to the Aegean Sea through the Dardanelles Strait.

• Location: Northwest Turkey, between the Asian and European parts of the country

• Connection: Black Sea → Bosporus Strait → Sea of Marmara → Dardanelles Strait → Aegean Sea

• Significance: It is the only sea entirely within one country that is historically and strategically important for trade and naval routes.
