visitcorinthia.comThe Submersible Bridge at Isthmia
At each end of the Corinth Canal stands a bridge that works the opposite way round to what you would expect: instead of lifting to let a ship through, it sinks into the water.
How it works
The bridge deck descends about 8 metres below the surface so vessels can pass over the top of it. Once the ship is through, the bridge rises again and traffic resumes. The whole thing takes a few minutes and is one of the most unusual sights in Greece.
Where to see it
There are two of these bridges: one at Isthmia (the eastern entrance, on the Saronic side) and one at Poseidonia (the western entrance, on the Corinthian Gulf). Both are freely accessible.
Practical notes
- There is no timetable — it submerges whenever a ship passes.
- Cafes and tavernas nearby make the wait easy.
- Combine it with the archaeological site of Isthmia and the Canal itself.
