The Faroes have built the world’s first undersea roundabout in the Eysturoy Tunnel – a massive 72 meters under the surface of the water.
It is an engineering masterpiece and also a phenomenal tourist attraction.
And considering it cost $265 million to build, you’d hope it was.

Officially known as the ‘Eysturoy Tunnel’, it was named after one of the two islands it connects.
The roundabout is at the centre of a two-lane highway that runs for more than 11 km (6.8 miles).
Obviously, the main attraction of the tunnel is the underwater roundabout.
The locals affectionately call it the ‘Jellyfish Roundabout’.

Building the tunnel was a massive undertaking and took four years in total.
The engineers had to come up with a clever system of pumps and pipes to filter rainwater and wastewater.
As for the roundabout, it was designed by Tróndur Patursson, a Faroese sculptor and artist.
It’s made up of a large steel sculpture representing people holding hands.


Eysturoy Tunnel price
This isn’t the only tunnel in the Faroes but it is by far the longest.
Unsurprisingly, it was also the most expensive.
With a total cost of $265 million dollars, this was the Faroe Islands’ largest ever investment.
There’s a $10 toll to cross the tunnel; revenue the Faroes use for other underwater projects.
About the Faroe Islands
The Faroe Islands is made up of 18 major islands as well as a number of smaller islands and rocks.
In theory, the archipelago is part of Denmark but it has its own government and language.
It even has its own currency, the Krona.
The islands are located in the North Atlantic Ocean, nearly 200 miles north of Scotland.
