The interior of the cave consists of a rectangular compartment, with a flat ceiling.
On the lateral walls, two arched niches are dug. The right one has a lithtic altar.
Opposite to the entrance, on the wall, a second masonry altar, surmounted by an arched recess carved into the rock.
It is said that in this central altar, when the cave was still open to worship, there was a canvas of the Virgin and on the lateral niches, two trunks containing relics.
