In short: By our ranking, the greatest engineering wonders in Greece are Corinth Canal, Chania Lighthouse and Diakofto–Kalavryta Railway. The list covers 5 engineering wonders. Last updated 13 October 2026.
Greece is a country of narrow isthmuses, rugged mountains and thousands of islands, and its engineering has always been about crossing water and stone. Ships needed lights on rocky headlands, island farmers needed the steady Aegean wind to grind grain, and the dream of cutting through the Isthmus of Corinth goes back to antiquity.
The Corinth Canal, opened in 1893, slices through the isthmus in a straight cut with near-vertical rock walls, completing a project that Nero had begun. The Chania Lighthouse stands at the end of the Venetian harbour breakwater, rebuilt in the 19th century in a slender, minaret-like form. The Diakofto–Kalavryta Railway uses a rack to climb through the narrow Vouraikos Gorge. On Mykonos, the Kato Mili windmills line a ridge above Little Venice, and the Tourlitis Lighthouse on Andros rises from a rock pillar in the sea below the island's main town.

It sounds like a straightforward ditch, but the isthmus rock is largely soft marl that slumps whenever it gets wet, which is why landslides still close the modern canal for repairs several times a year — a problem Nero's engineers had already run into and modern ones still haven't solved.
Did you know? The finished channel runs about 6.4 km between walls of rock that climb to roughly 90 metres, cut at an angle close to vertical.

The site has been guarded for centuries. The Venetians, who ruled Crete from the thirteenth century until 1669, built the harbour defences and a first lighthouse here to protect the port against pirates and the Ottomans. After the Ottoman conquest of Chania in 1645 the light fell into ruin.
Did you know? Under Ottoman rule the old port and its light were neglected because the new rulers preferred the deep natural anchorage of Souda Bay nearby.

The line was part of the ambitious plan of the prime minister Charilaos Trikoupis to connect Greece by rail. It was built by a French company with Italian craftsmen who had learned their trade on Alpine railways, and it opened on 10 March 1896 as a branch of the Piraeus, Athens and Peloponnese Railways — for its time one of the most difficult pieces of engineering in the country.
Did you know? The original plans foresaw continuing the line beyond Kalavryta to Tripoli, but the extension was dropped for lack of money before any work began.

Their shape is the standard Cycladic type, and it was shaped by the weather. The towers are round, two storeys high, built of stone with whitewashed walls and only the smallest openings, and most face north, into the wind that blows hardest over the island for much of the year. Construction began under Venetian rule in the sixteenth century and went on into the early twentieth.
Did you know? Much of the flour was baked into paximadi, hard twice-baked rusks that kept for months and fed sailors on long voyages.
Τουρλίτης

The first light on Tourlitis was lit in 1897. During the Second World War, in 1943, the tower was flattened in a German air raid, and for decades afterwards only a plain iron framework marked the rock.
Did you know? Locals also know the rock and its light by the name Tourleta.
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
