The archaeological site of Cueva de Las Monedas

The Cueva de Las Monedas is an archaeological site located within the cave complex of Monte Castillo in Puente Viesgo, Cantabria.

Discovered in 1952 by forest ranger Isidoro Blanco Fernandez, the cave features a small vestibule that leads to a large network of rooms containing stalagmites, stalactites, and other typical cave formations.

The most significant study of Las Monedas was published in 1972 by Eduardo Ripoll Perelló, which documented materials from the Bronze Age and the Iron Age, as well as some Paleolithic lithics and some coins that had been hidden during the era of the Reyes Católicos. The cave also contains a large number of black rock paintings representing horses, bears, goats, and other figures similar to those found in the region.
