Which canal connects the Aegean Sea with the Gulf of Corinth?

The Corinth Canal connects the Aegean Sea with the Gulf of Corinth. It cuts across the Isthmus of Corinth in Greece, separating the Peloponnese from mainland Greece and avoiding the longer route around the peninsula.

Construction began in 1881 and the canal opened in 1893. It is about 6.4 kilometres long, but its narrow width limits the size of ships that can use it. The steep rock walls rise dramatically above the waterway, making it one of Greece’s most recognizable engineering landmarks.

Ancient Greeks considered the isthmus strategically important and used the Diolkos, a paved trackway, to move vessels or cargo across land. The modern canal is not a sea strait: it is an artificial waterway excavated through the isthmus.
