Take a tour of Corinth Canal in Greece – part of the World’s Greatest Attractions series by GeoBeats. The canal is about four miles long and has walls that are merely 80 feet wide. The distinctive Corinth Canal is the realization of over 2,000 years of vision. The Gulf of Corinth had long been separated from the Saronic Gulf by the Isthmus of Corinth. Before the construction of the canal, ships had to sail around the Peninsula. Many rulers, from Periander to Julius Caesar to Nero, proposed a canal, but never built it. Finally, in 1893 a Greek company completed the Corinth Canal, allowing the boat traffic through.
