Hey kiddo, do you know what a strait is? It's like a very narrow path of water that connects two bigger bodies of water.
The Strait of Otranto is a strait located between Italy and Albania. It's like a big doorway that connects the Adriatic Sea (that's the bigger body of water above the strait) to the Ionian Sea (that's another bigger body of water below the strait).
The strait is important because it's the only entrance from the Adriatic Sea to the Mediterranean Sea. And since people have been traveling by boats for a very long time, this strait has been used as a pathway for trade and commerce between countries.
But, it's also a dangerous place for ships to pass through because of strong currents and winds that occur in the area. Plus, during wars, the strait has been used as a strategic point to control access to the Adriatic Sea.
So, the Strait of Otranto might just look like a narrow strip of water on a map, but it has played a significant role in history and continues to be important for trade and transportation between Italy and Albania.
