Sea of Marmara

sea in the northeastern part of Turkey (near the borders of Greece and Bulgaria)

n. inland sea in north-west Turkey connected to the Black Sea by the Bosporus and connected to the Aegean by the Dardanelles

The Sea of Marmara (Turkish: Marmara Denizi, Greek: Θάλασσα του Μαρμαρά or Προποντίς, Bulgarian: Мраморно море), also known as the Sea of Marmora or the Marmara Sea, and in the context of classical antiquity as Propontis (Greek: Προποντίς), is the inland sea that connects the Black Sea to the Aegean Sea, thus separating the Asian part of Turkey from its European part. The Bosphorus strait connects it to the Black Sea and the Dardanelles strait to the Aegean. The former also separates Istanbul into its Asian side and European side. The Sea has an area of 11,350 km².
