Corinth Canal -

The Corinth Canal (Greek: Διώρυγα της Κορίνθου, Dhioryga tis Korinthou) is a canal that connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, thus effectively making the former peninsula an island. The builders dug the canal through the Isthmus at sea level; no locks are employed. It is 6.4 kilometres (4.0 mi) in length and only 21.4 metres (70 ft) wide at its base, making it impassable for most modern ships. It now has little economic importance.
