The mysterious spring that expels water and no one knows where it comes from

It remains a mystery. Even with current technology, it hasn’t been revealed yet. The craziest theories follow one another about its origin for centuries. And three people have lost their lives trying to get to the bottom – in this case literally – of the matter.

It is the underground spring known as It was Dionne in the French region of BurgundyIt was during the Roman Empire that a city was discovered and created around it, which today is the city of Tonnerre.

The impressive stream of water that emerges has amazed for centuries. The Celts considered this source sacred and the French used it as a public swimming pool during the 18th century.

Today expels 311 liters of water per secondalthough it can reach 3,000 on rainy days, and no one has been able to find out where it came from.

From the 18th century, the intrigue began to discover the source of this large amount of water. Some claimed it was a portal to another worldwhile others were convinced that its bottom housed a giant snake.

The charm has grown over the years; Y In 1974, the first attempt at discovery was made once and for all the origin of spring. It was two professional divers who ventured into the narrow passages of limestone rocks.

But it turned out to be much more difficult than he thought, even for experienced divers like the two men who plunged into the shaft, and both are dead.

It would take 22 years to make a new attempt, which had the same tragic outcome. It was 1996 and that time it was the city of Tonnerre itself that hired another diver who also drowned in an attempt to uncover the mystery.

But it seems the fascination with this conundrum is still as strong today as it was millennia ago. because last year the mayor of Tonnerre returned to office.

It was professional diver Pierre-Éric Deseigne that the head of the city was looking for to solve the mystery.

designate it fell almost 75 meters deepventuring more than 370 meters from the entrance to the cavity, but was unable to reach its origin, and had to return when his life began to be seriously in danger.

It is known the water emerges from a network of underground caves of limestone, but in this case no one has been able to locate its origin. And it is probable that no one wants to try again, even if knowing us it is doubtful.
