This is the lowest level of the quarry. The ceiling is low because there is a level just above. The quarrymen have not dug lower because of the proximity to the Seine.

In the quarry of Meudon Montalets. The five quarry levels.

We used to come to rest in this beautiful round room during our visits to the quarry. The hole in the center of the room no longer exists. At left, behind the door, there's a view of the corridor from the heights.

On the ceiling there is a site for a large beam. There was probably a winch.

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.
