The cave of the "concarelle"

That is a small hollow: the outcome of a fossil upwelling.

It had been early portrayed in a cartography designed by Diego de Revillas in 1735 and belonging to the Diocesi dei Marsi.

Later it will be described  and reproduced in a topographical map designed by Carmelo Mancini and published in the Bullettino Archeologico Napoletano in 1859.

The so called “gours”, known as “concretionary bowls”, are very interesting because of their peculiar origin. In fact, they are real “dams” that collect the outflow and the dripping of waters.

Their winding course is controlled by the rock unevenness, on which they lie and by the power of the water that flows: the larger the quantity of water, the less winding those barriers become.

Popular tradition considered them as the places of rest for the workers who, firstly, bored the underground tunnel of Fucino.
