Plus unclassified remains of the Neolithic, Chalcolithic, Bronze and Iron ages.
It is best known for its mural paintings of the Magdalenian period, depicting bisons, horses, goats and deers.
Its excellent location over the Urdaibai estuary was probably most important in its continued habitation, first by Neanderthals and later by Homo sapiens.
