The diameter and depth of the chasm are impressive. It's scary. I advise caution in the cold months (and not only) as there is ice everywhere and the area becomes a skating rink, although there are protective barriers. I speak from lived experience....

Impressive and spectacular sinkhole of karst origin, which descends as a well for 46 meters, then continues with a lateral corridor and falls with another well, reaching the overall depth of -96 meters! The dark and mysterious mouth is illuminated by a natural skylight dug into the karst ceiling. At the bottom of the cave the ice remains throughout the year.

It is called indiscriminately Caverna or Voragine (del) Siesòn or Sciasòn.
