The cave of Sanguineto owes its second name "della Matta" to a poor demented woman who had found refuge there during the nineteenth century. It opens in the limestone ridge of Finale at an altitude of 175 meters above sea level on the mountain that divides the Aquila Valley.
The large oven-shaped opening of 22 metres by 6 metres in height leads inside the cave into a large room with a dry and dusty ground, about fifteen metres deep, which ends in a large landslide.
To the left of the entrance a narrow tunnel 60 centimetres high (to be covered for at least 6 metres at "leopard's step") about 18 metres long allows access to an internal room with a vaguely quadrangular shape of 15 metres on one side, with an irregular bottom. In this room archaeological materials have been found below the stalagmite crust. Overall, the Sanguineto cave is the third cave in the Finale area, after the Arene Candide and the Pollera, due to the importance of its frequentation. (OPENSPELEO 2008)
