A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. The Strait of Otranto connects the Adriatic Sea with the Ionian Sea. It separates Italy from Albania. Its width at Punta Palascìa, east of Salento is less than 72 kilometres (45 mi).The strait is named after the Italian city of Otranto.

Since ancient times the Strait of Otranto was of vital strategic importance. The Romans used it to transport their troops eastwards. The legions marched to Brindisi, and had only a one-day sea voyage to modern Albanian territory. During WWI, the strait was of strategic importance. The Allied navies of Italy, France, and Great Britain kept the Austro-Hungarian Navy from freely entering the Mediterranean Sea.The blockade was known as the ‘Otranto Barrage’. However, the barrage was notoriously ineffective against the German U-boats operating out of the Adriatic.

The Strait of Messina, is a narrow strait between the eastern tip of Sicily and the western tip of Calabria in the south of Italy. The Strait of Bonifacio is an international strait separating Sardinia from Corsica whichit enables communication between the Sea of Sardinia and the Tyrrhenian Sea. The Straits of Corfu is the narrow body of water along the coasts of Albania and Greece to the east separating these two countries from the Greek island of Corfu on the west. The channel is a passage from the Adriatic Sea on the north to the Ionian Sea.
