The Corinth Canal in Greece is a deep-ditch ship canal, connecting
the Ionian and Aegean seas. Built between 1882 and 1893, the canal is only 4
miles (6.3 kilometers) long. But for most ships, it saves a 202-mile (325-kilometer)
voyage around southern Greece. The canal has no locks because its entire length
is at sea level.
