The Paris underground ossuary and the huge network of passages, sprawling in the belly of Paris. The total length of the strokes in the tens of kilometers. The initial origin of the workings associated with the extraction of limestone, is under a large layer of soil. The average depth of excavation is about 25 meters. This is far below the level of the Paris sewers and subway. Network moves mostly concentrated in central Paris.Scheme of the catacombs. The winding sections - the old system (end of XVIII century), direct - a new (mid-XIX). The new system is more monolithic. Hewn stones, straight narrow passages, tracing which almost coincides with the trace of the streets. There is also a branch in the groundwork and third-party drifts. Provided for ventilation. mine. The old system is more chaotic, masonry laid out along the passage is not squared, sinuous moves. Here is a great number of branches and backlog. But the interesting thing in her belly, about it later.

For a very narrow spiral staircase down to -10 m. This mark is a small gallery and a new entry to the level of ~ minus 25 meters.
The first impression is a bit ordinary. I was expecting to see something in the likeness of suburban systems. Everything is much more civilized.
Some of the basements of houses standing on top connected to the system.
These corridors are flattened tens of meters to a variety of inputs, gradually merging into one channel (in the form of Christmas trees)
One of the drifts with access to the basement.
Often not hewn masonry
Earlier this place was a small room, but in the mid-20th century, it partially collapsed.
This is a common pit. A little strange to see him here.
A sign on a pillar on the right reads on the date of burial.
