note from the end of the nineteenth century, was among the first to be explored on the Carso of over 3,000 caves currently stacked. Today the inputs are two: a natural well deep about 30 meters, from which it is possible to dive only with speleological equipment, and an artificial input which, through a staircase of 200 steps, leads the public to the heart of the cave, about 60 meters below ground.
The cavity extends into compartments adorned with beautiful sails, eccentric, stalactites and stalagmites, high up to 7 meters and are also heavy 10 tonnes. The most famous are the towers stalagmitiche, a group of eight concretions of different sizes, from which the grotto takes its name. Inside, besides the small insects typical of the hypogeal environment, dwells in a mixed colony of bats: three species living, become lethargic and reproduce in the cave. These are protected by a partial lighting of the cavity and by specific requirements that govern the flow of visitors on the basis of the rhythms of nature.
The cavity is an example of active protection of a naturalistic site born from a close collaboration with the Natural History Museum of Trieste and with the Faculty of Geology of the University of Trieste. The inlet includes: Guided visit with a naturalistic guide or speleological; transport Agribus with at the entrance of the cave and return; endowment of safety helmets with lamp.
