The famous Corinth canal in Greece connects the Saronic (Aegean sea) and Corinth (Ionian sea) bays. A channel dug across the narrow the isthmus of Corinth, thus separating the Peloponnese from mainland Greece.

The idea of the construction of such channel was debated even in ancient times. The first written mention of the possible construction relate to the period of the Corinthian tyrant Periander (7th century BC). Then for various reasons the project was abandoned and built over a simple and cheap land portage (its remains can be seen near the channel and in our days). A new round of possible construction emerged in the year 307 B. C. the Initiator was Demetrius the poliorket], but the engineers, whom he invited for carrying out the work, convinced him of the inevitability of catastrophic consequences, as the water level in the Saronic and Corinthian gulfs were not the same.

The first thorough attempt to build the canal was undertaken by the Emperor Nero in the 1st century ad Construction began in 67 ad, but after the death of Nero expensive project was abandoned. Later, some attempts have also been made by Geroda Attic, Byzantines and Venetians, who, however, did not succeed.

Revived the idea of building a canal after the Greek revolution. Oversaw the issue of the Greek statesman Ioannis Kapodistrias. But after calculation and estimate documentation, it became clear that it was too expensive a project for the young state and temporarily abandoned. After the opening of the Suez canal in 1869, the Greek government issued a law allowing the construction of the canal. In may 1882, after a long preparatory work, the construction finally began. After many obstacles, including financial, 11 years later in 1893, the Corinth canal was put into operation.

The length of the Corinth canal is 6, 4 km, depth 8 m, and its width is 21, 3 m at the base and about 25 feet above sea level. The canal connects the railway bridge and three road.

Today, because of not enough bandwidth and, as a consequence, the impossibility of passing through a large modern ocean-going vessels it lost its economic importance. In our days, the Corinth canal is used mainly for various tourist boat.
