Back in 2005, hundreds of people in Spain were stuck in the world’s most peaceful traffic jam, but in this case, they had no reason to be angry.
Surrounded by the lush green landscapes and towering beautiful mountains of the Spanish Basque Country, it seemed like this gigantic tailback formed out of nowhere.
That’s because it did. And it was probably the most peaceful traffic jam that has occurred anywhere on the whole planet.
Spanish artist Maider López invited anyone with a car to meet her in the Basque mountains for an art project taking place in the middle of nowhere.

If you were traveling through the lush green countryside and mountains of Spain, the last thing you’d expect to find is a traffic jam that rivals those in a built-up suburban city.
Well, in 2005, if you decided to visit the winding mountain road that led up to the Aiako Harria Natural Park in the Basque Country of Spain, then that’s exactly what you would have stumbled across.
This traffic seemingly started out of nowhere and was caused by nothing. But no one seemed angry or was in a rush to get out of it.
That’s because everyone in that traffic jam went willingly, invited there by Spanish artist Maider López, who had asked anyone with a car to meet her there for an art project.

Arranging the 160+ vehicles by color, López formed a traffic jam deep in the lush countryside. And she encouraged the participants to chat, stretch, and interact as normal, pretending to wait for it to clear.
Her reasoning? She wanted to put a common urban nuisance into an untouched and beautiful landscape, forcing us to see something so commonplace in a different light.
Maider wanted people to know that it wasn’t art about cars or people. It was about what it means to be stuck together and how we interact with the world.
Maider López simply named the project ‘Ataskoa,’ which is Basque for traffic jam. And this simple concept still causes people to stop and think two decades later.
