The site consists of a series of rock carvings, discovered in 1988 by professor Manuel Santoja y Rosario Pérez, during an inventory campaign of archaeological sites in the valley of the Águeda river. Subjects include horses, goats, bulls and deer, among the most common ones, as well as bison, reindeer and the woolly rhinoceros, which were not yet extinct at the time.
The engravings date to the Gravettian culture of the Upper Palaeolithic (circa 20,000 years ago). There are also more recent, anthropomorphic representations, dating to the Magdalenian age (c. 12,000 years ago). There is a total of 94 panels, spanning some 3 kilometers of rock.
