In the Arpán canyon, tributary of the River Vero, is a unique site known in Aragon for its paleolithic cave paintings.

It is a deep shelter, in which only indirect sunlight penetrates. Its opening is orientated towards the east and in front of it is a spring (“fuente”), which gave the cavity its name.

During the paleolithic era, the cave was used as a temporary shelter during the coldest months of the year. Humans gained access to this site after following the movement of wild animals, that they were hunting.

The walls contain paintings from the Upper Paleolithic era (around 22,000 B.C.E), depicted in black and red, cave engravings and remains of what was the settlement on the site. The latest research and dating indicate that the collection is the older than it was previously thought.

Successive excavations have permitted the recovery of several instruments carved from flint and quartzite, as well as the remains of wild animals, such as horses. A fire heater, which has few parallels in the Iberian peninsula, was also found.

Given that currently it isn't possible to visit the interior of the cave, there is a recreation of it in the Cave Art Centre, in Colungo
