Cueva de Ardales is a hugely important Paleolithic site in Malaga, Spain, owing to its rich inventory of rock art. According to new research, Neanderthals entered this cave in the Middle Paleolithic, over 65,000 years ago and left traces of symbolic practices on the cave walls; thereafter the cave was repeatedly visited by Homo sapiens all the way to the Late Neolithic/Chalcolithic period.
