The famous Corinth Canal connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea.
The canal is 6.4 kilometers in length and only 21.3 meters wide at its base.
Earth cliffs flanking either side of the canal reach a maximum height of 63 meters.
Aside from a few modest sized cruise ships, the Corinth Canal is unserviceable to most modern ships.
The same fear also stopped Julius Caesar and emperors Hadrian and Caligula.
The most serious try was that of Emperor Nero (67 CE).
He had 6,000 slaves for the job.
He started the work himself, digging with a golden hoe, while music was played.
However, he was killed before the work could be completed.
But the budget, estimated at 40 million French francs, was too much for the Greek state.
The job was finally completed and regular use of the Canal started on Oct 28, 1893.
It is now used mainly for tourist traffic.
