The Corinth Canal is an artificial waterway connecting the Ionian Sea’s Gulf of Corinth in the northwest with the Aegean Sea’s Saronic Gulf in the southeast. The canal passes through the narrowest portion of the Isthmus of Corinth separating mainland Greece from the Peninsula of the Peloponnese.
Work on the canal began in 1882, and it opened in 1893. With its 6,3 km long, the Corinth Canal provides a shorter navigational route to the west from Athens and the port of Piraeus and saves up to 350 km detour.
