Living quarters The living quarters with the alcoves for the water supply (on the left) and for the air purifying system (on the right), looking toward the entrance (24/06/1999).

The living quarters are located at the end of the main corridor and, together with the corridor after the steps, constitute the underground part of the works.
The shelter room was equipped with an alcove for the water supply located near the entrance, and with a ventilation and air purifying system located half-way against the opposite wall.
The high level of humidity and the winter freeze have caused the plaster to fall off the walls.

Remains of the power supply system on the right wall of the alcove of the air purifier. Notice the water drops hanging from the ceiling (24/06/1999).
