Quarry of Montrouge Chatillon Malakoff

Fish bones (also abbreviated ADP) are part of a network of much larger gallery, called Fantasques, due to the name of a road, above the galleries. As its name suggests, the network looks vaguely to a structure of a wheat. In fact, it is a network of parallels arranged around two dorsals (or main roads) with an orthonormal structure, much like certain Nazca archaeological symbols, or even a TV antenna, but definitively not like fish bones.
The main feature of these undergrounds is their purpose was not to drain water, unlike the other two parts of the network (The Colinettes and large galleries). Most galleries are straight, flat, millstone, with dry soil, with the notable exception of the main corridors, steep slope with many stairs.

One of the tanks on the top floor, with plumbing. It is assumed that this was the source of drinking water from underground center.

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 ...

Aquatic center abandoned of Chevry

In 1987, the council is negotiating with Compagnie Generale des Eaux construction of an aquatic center. In 1988, the new aquatic center is opened. The private company obtains a contract of 30 years, with the obligation to provide a public service for city schools.

After four years of operating deficits, the company Aqualand calls for an end of the concession January 31, 1993.

On 1 February 1993, the mayor bought the equipment and Aqualand becomes Aquagif.

Until 1997, the institution's financial health is sound. From 1998, a report from the Audit Office highlights a deterioration brought on by poor weather, increased personnel costs and expenses of heating and hot water (IFR200240 report).

The report also states that the municipality has used various means to hide the difficulties of the institution (Former Mayor Robert Trimbach will defend itself in its response to the use of a policy of long-term. IFO27010301 Report.)

Summer is the period which brings the most money and serves to balance the books. However, in May 2002, just before the summer, the aquatic center closes down.

An auction should take place but the building was battered scrap dealers. Christmas 2003, when the building is almost completely demolished, one can still see all the devices in the gym, ready to be thrown in the trash.

This place was called "The Station" by the group of explorer "shills". The rails are still under water to some completely flooded. It takes a boat to access this part of the underground quarry.

The workers have mounted a wall and scaffolding have large green tarpaulin over which water flows continuously. Thus, a lot of construction dust are recovered. Note that right side is a maternity ward.

Quarries of Paris - The fountain of the Chartreux.

The Fountain Room of the Carthusians was built in 1819. The order of Carthusian monks had disappeared during the French Revolution. There is a magnificent double staircase which gives access to the fountain. Further, a low water level is used to measure the height variations of the water table. The fountain was built by the Inspectorate General of underground quarries to supply water to underground workers.nterirdischen Steinbrüche gebaut, um Wasser in die U-Arbeiter zu versorgen.
