Along the tunnel you came up against an artificial water reserve, created cementing the bottom of an old gallery and building in the anterior part a containment wall. The water from the " troppo pieno" is sucked by a pump and brought to the level" Paola", where it feeds another small reserve.
The water arriving here auto-purifies through filtering, and it is therefore possible to observe the reflexes of the overlooking marble vault.
