“One of the finest painted caves, and also one of the first to be discovered (in 1879). The site is south of Santander, in northeast Spain, and is famous for its polychrome animals , which include deer, bison, and wild boar painted in red, black, and a range or earth colors. Most of the art in the caves was produced by Magdalenian peoples.”
