Northern Spain’s magnificent collection of 17 caves with Cro-magnon artworks have recently awarded the status of Unesco World Heritage Site, in fact Altamira, the jewel in the crown, has enjoyed this status for some years . The caves are spread along the coast from the Basque country, through Cantabria, where the highest concentration is to be found, to Asturias and they lie mostly between the Cordillera Cantabrica and the sea, making a visit easy to combine with a great seaside holiday.
