Corinth Canal Greece

Greece

The ship slows to a walker's pace, and silence falls on the decks. Before the bow opens a rectilinear trench cut into rock, so narrow that travellers on either side can almost touch the wall with their gaze. Passing through the Corinth Canal resembles no other navigation: for 6.4 kilometres, you glide between two walls of limestone that separate the Peloponnese from mainland Greece.

A Dream Twenty-Six Centuries Old

The idea of piercing the isthmus dates to Periander, tyrant of Corinth in the seventh century before our era. Faced with the work's magnitude, he preferred to have built the diolkos, a paved causeway on which ships were hauled from sea to sea. Nero launched digging work in the year 67, golden pickaxe in hand according to legend, before the project died with him. It took until 1893 for the breakthrough to finally complete, making the Peloponnese a technical island linked to the mainland by a few bridges. Twenty-five centuries of attempts for six and a half kilometres of rock: few works so well sum up human obstinacy.

The Passage, Minute by Minute

The crossing is made in one direction, by convoys, and ships of a certain size advance behind a tugboat. With a width of scarcely more than 21 metres at the base, the channel admits only narrow hulls: the Braemar, a 195-metre ship carrying about 900 passengers, set the record in October 2019 for the longest vessel to squeeze through, with a margin of only a few dozen centimetres on each side. From the upper deck, you see the rock's strata file past, the road and rail bridges suspended above the masts, and sometimes the tiny silhouette of a bungee jumper saluting passengers.

A Work Become Spectacle

Commercial traffic abandoned this passage long ago—too narrow for modern cargo ships: about 15,000 vessels still use it yearly, chiefly sailboats, yachts and exceptional units. The canal lives today on its own legend, and it wears it well. Passengers crowd forward at the passage's announcement, cameras rise together, then surprising calm settles in: you hear water against the hull and shipboard commentary, nothing else. Some captains tell the story of the piercing over the loudspeaker during the crossing, and the history takes on another dimension when the walls file past metres from the balconies. The best spots are right forward or right aft, where the trench's perspective stretches from gulf to gulf.

Ancient Corinth: Steps from the Trench

Itineraries using the canal often propose a stop or excursion toward ancient Corinth, very close by. The city was among Greece's mightiest: its agora, its Doric columns of the Temple of Apollo and the Pirene Fountain stand at the foot of Acrocorinth's rock, a natural fortress overlooking both gulfs. Saint Paul preached there and wrote; readers of his epistles walk here in a setting that has remained astonishingly legible.

A Few Numbers to Measure the Achievement

On the Other Side

Then the walls draw apart, the sea reclaims its rights and the ship regains its cruising speed as one catches one's breath. Many remain leaned against the rail for a moment, watching the slit close in the coastline. Few maritime experiences fit into twenty minutes and are told for years afterward; this one does, and it gives you the desire to see what Greece holds at the next turn of the voyage.
