One of the most interesting plates of the official ossuary. This part of the catacombs is hidden to the public.
It is inscribed "Catacombs low" while the corridor descends into a lower part of the quarry. The bones are placed in bulk.

Our base camp in the very end of the quarry.

This graffiti is the last in the series about death in this corridor.

Many concretions in this part of the quarry Keppler.

At several places in the underground quarry, drawings of boats, very old.

This pillar is thin, although it is cut in the ground.
