Cantabria has the highest density of caves with cave paintings in the world and has over 60 with paintings on its walls. Altamira and the other nine cavities that are UNESCO World Heritage Sites are the universal symbol of this valuable legacy from the Palaeolithic Age that coexists with another no less surprising underground legacy: the more than 6,500 caves with breathtaking geological forms and spectacular landscapes, such as El Soplao.
