Prehistoric rock art on the shores of the Cantabrian Sea.

Designated World Heritage in 2008

It is 300 metres long and has Palaeolithic cave paintings on one of its walls. It is in a stunning location with cliffs running down to the sea. Inside is one of the most beautiful examples of Palaeolithic art to be found in the region, with a duo comprising a horse and bison as the main motif. It has images of a fish and a mammoth, representations that are infrequent in the Palaeolithic art of the Cantabrian coast, which makes them particularly interesting. From the technical point of view, the engraving work mixes together shades of red and black. Their estimated age is between 13,000 and 18,000 years.
