Cantabria has archaeological sites from the Upper Paleolithic period, although the first signs of human occupation date from the Lower Paleolithic. The most significant site for cave paintings is that in the cave of Altamira, dating from about 37,000 BC[8] and declared, along with nine other Cantabrian caves, as World Heritage Sites by UNESCO.

There is a heavy presence of fabulous beings of giant proportions and Cyclopean features (the ojáncanos), fantastic animals (culebres, caballucos del diablu (lit. horses of the devil, damselflies), ramidrejus, etc.), færies (anjanas, ijanas of Aras), duendes (nuberos, ventolines, trentis, trasgus, trastolillos, musgosu, tentiruju), anthropomorphic characters (the sirenuca (little mermaid), the fish-man, the cuegle, the wife-bear of Andara, the guajona), etc.

“Divinization also occurred with respect to rivers and bodies of water. At Mount Cildá there was an area dedicated to the mother goddess, Mater Deva, a personification of the river Deva. At Otañes there was a ritual took place dedicated to the nymph of a spring that had medicinal properties. Pliny the Elder[9] mentions the existence of three intermittent springs in Cantabria. The Tamaric Fountains were worshiped by the Cantabrians as a source of prophetic omens. Pliny recorded the existence of three fountains near one another whose waters joined in one pond. There, the flow would stop for between 12 and 20 days. The cessation of the flow was interpreted by the people as a negative sign.”
