An orientating room in the rooftops of the Samaritaine store, formerly available to the public ...

"The large sink" or "room of hanged people" is the locker room of minors. Besides saving space to hang clothes by a chain (with a padlock attached to the benches), the upper part of the room was warmer, facilitating the drying of clothes.

The large rooms upstairs 27bis of the tower CB31 are equipped with acoustic panels to eliminate echoes.

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.

This part of the cathedral is more modern. In fact, it's the boiler room of the cathedral that has been camouflaged. In cold weather (below zero), a large plume of steam rises and can spin like a snake between the columns to the side. It's pretty fun, unless you want to take pictures.

Mushroom area in a gypsum quarry, exploited on stacks

The SEBILLOTTE quarry was operated from 1838 until 1940. Then, the quarry has been used for growing mushrooms until 1960. There are still beautiful mushroom beds in most rooms of operation.

This corridor is almost completely around one of the last level gave me the solution to the legend that surrounds the courthouse in Brussels. Indeed, the legend says there are so many rooms that nobody really knows the number. It would suffice to count them you say? Certainly, but the legend also says that some rooms are hidden! And it's true! This corridor will lead to narrowing to a dead end. But shortly before, once a straight line (since it is the turn of the last square base, so that makes 4 times) there is a steep staircase, added a bit anyway, which is sometimes blocked the passage a pipeline. This staircase leads into empty rooms mysteriously seem to have been recently refurbished (light, electrical outlets). Impossible to know what they were good or what they will be used, it is already difficult to access with empty hands, imagine the trouble we have to make a table! No other access to these rooms, no windows.

The sports stadium in Bordeaux was built from 1959 to 1966. It is up to the late 1970s, used as major sporting events but in 1979, the city transforms the room with acoustic treatment. The sports hall can accommodate singers. Today is a secondary hall of the Opera of Bordeaux and there is more sporting events in this room.

This room was called the Grand Rex because of his height and the sloping floor in tiers remembers a famous parisian movie theater. In winter, there are many bats in this quarry, thank you not to disturb them!
