A week ago a new rock art site was revealed to exist right in the town of Lekeitio (Biscay). The art, estimated to be from some 14,000 years ago (Magdalenian culture), is made up of several groups of engraved animals: bisons, horses, goats and deers. The cave is not far from other known sites like Lumentxa, Atxurra and Santa Catalina.
