This tank is a false tank that served as a film set. She was left in place after the shooting.

The Degond factory is one of the oldest factories of Longueville. She moved strategically close to the station after the track railway completed. It will employ up to 800 people in the village of Longueville and surrounding areas in manufacturing seamless tubes by stretching, before closing in 2003.

The decontamination and demolition of the site would cost more than 5 million euros. The company had already been convicted in the 1990s due to pollution of the river near the village: The Voulzie. Concentrations of hydrocarbons and chlorinated compounds detected in 2007 are still worrisome.

The origin of the silver-lead mines Trémusson is Roman. It was already long pieces of Roman origin in the galleries. An excavation site has confirmed the original site, by the discovery of tiles to hook on both sides of the creek.

In the late 17th century, the English are precursors in the mining of nonferrous metals. They buy logging concessions in Britain. However, the site is still not exploited Trémuson. The concession is then awarded on 1 April 1732 to a Breton of Morlaix Guillotou of Kerver. Speculation around the precious metal is growing, which does not prevent the owner from going bankrupt due to a bad investment.

In 1740 the Mining Company of Lower Britain bought the concession. It will take 40 years to industrialize the mines. In 1782, more than 500 people work at the mine site. The size of the concession is over 90,000 hectares. It will never be fully exploited. At the end of the 19th century, the exploitation fall. The owners regularly change without success.

It was not until 1922 that the operation resumes. A laundry room is built on a hillside in 1924. She can wash the ore and the sort because the deposit is less rich than in ancient times. A year later, a foundry was built. The operation is successful for ten years, then the company suffers Dufourg the general crisis. In 1931, the mine was permanently closed. It will never be exploited.

Today, the mines are protected refuges for bats but the many miles of tunnels continue to drain the lead in the village by water infiltration. The villagers can not eat vegetables from their gardens or drink water polluted groundwater. There are remains of the laundry and the foundry behind the village.

One of the many leaflets Claustrophile long to read.

I feel lonely. Sitting on the edge of a puddle, waiting night after night came from an image, even furtive, which will warm my frozen heart. Boredom is deadly but I am perhaps more myself.
I do not control my movements. It seems I am doomed to remain motionless near the puddle. I can sit there, going to bed at the top in every sense, to slip under the surface. But I can not go away. Several weeks have passed already, maybe more. I lost track of time. I also lost touch and smell.

It all began one evening in July, right here. I rode north through here. I walked into the puddle and I did not immediately understood what was abnormal about it opposed the reaction to my muddy boots. In retracing my steps that I understood, without understanding anything beyond. The water that I had defiled was perfectly clear! I did another test, stirring the surface with my dirty soles. But water does not disturb and do not wash my boot. Worse, it penetrated the boot but no step had resulted. I started to jump in with both feet, there was no splash. I thought mad.
I think when I last had committed error in allowing my curiosity until that train was going to lose. I squatted and I plunged his hand into the water. I could see through transparency, I felt the cold touch and wet. But the water do not wobble. If I was raising in my palm and I let her run, she immediately incorporated the puddle remained perfectly motionless. I was scared.
But after a few minutes I emerged reflects a man who looked at me. I was scared to see it without having heard it, but it was nothing of the horror that awaited me next. Because when I turned around there was nobody behind me. This man existed only in reflection. And only in this puddle. I saw him once. It was already too late.
I was terrified. The stranger in the mirror and spoke agitated, as if trying to tell me something. But he remained silent to my ears. I panicked. I wanted to run but I was so scared I did not notice the sky of the quarry. I myself am hit with unprecedented violence. I think the shock was fatal.
Where I felt back up, I saw myself lying with his head in a puddle of blood flowing to the puddle of water. But when I looked at the puddle that is me that I could not see. I had no reflection.
The body was lying nearby was finally identified but it was not mine wearing my clothing and my backpack.
It was the man I saw in the reflection! He set off again in flesh and blood, for me, leaving me alone and trapped in my fate! I could not even follow him, as if the puddle of water had been magnetized. Since I am still waiting in the darkness, someone realizes that the puddle is still ...

Maybe you than I expected. You who picked up this pamphlet, a little better scans the surface of the water ...
