Cave of Altamira, Santillana del Mar, Cantabria.
Doubtless, it is the cave with the most important paleolithic rock art in Spain and one of the most well-known in the world. Its walls have beatiful pictures on bisons, deers, horses...
It has been called the "Sistine Chapel of rock art”.
Cueva de Altamira

It is ca. 310 ms long, with an entry that leads us to a "hall". This hall communicates through its left and bottom side with a room decorated with the big panel of polychromes.
This gallery goes on with many and different graphic representations. It ends in a wide room called “La Hoya” -the hole-. La hoya gives place to a new narrow gallery called "Cola de Caballo" -horsetail-.
Because of researchs and public old visits, the cave has been spoilt: not only in its pictures, but also in its structure. Today many "works for restoration" try to assure its preservation.
