The Great Hall of Polychromes is the best-known and most iconic part of the cave of Altamira. It includes images that are figurative and abstract, engraved, drawn, and painted, in black and red, covering a wide period of time from at least 36,000 years ago to the time of the collapse of the cave entrance around 13,000 years ago. Acting as a large canvas, its surface is the meeting point on which the different groups of people who inhabited the cave, from the Aurignacian culture to the Magdalenian culture, expressed themselves.
