The Corinth Canal
The Corinth Canal is a waterway that crosses the narrow isthmus of Corinth to link the Gulf of Corinth to the Saronic Gulf. As such, the canal separates the Greek mainland from the Peloponnese, turning it into an island
The canal, though executed in the late 19th century, has been a 2000-year-old dream. Before its construction, ships in the Aegean Sea that wanted to cross to the Adriatic or anchor in Corinth, a rich shipping city, had to circle the Peloponnese, which would prolong their journey an extra 185 nautical miles.
It is believed that Periander, the tyrant of Corinth (602 BC), was the first to conceive of the idea of digging the Corinth Canal. As the project was too complicated given the limited technical capabilities of the times, Periander constructed the diolkos, a stone road which allowed ships to be transferred on wheeled platforms.
