The prehistoric Altamira Caves are among the most famous in the world. Discovered in 1879, they are made up of various galleries with paintings and engravings on the walls dating back to the Solutrean age. The original caves can no longer be visited, in order to protect and preserve them, but you can take a guided tour of the site, dedicated to the prehistoric world, where this is a replica of the cave, called "neocueva" and a very informative museum, presenting the art and way of life of Paleolithic humans.
