It is one of the most important rocky shelters of the site, and perhaps of the northern zone of the entity, due to its archaeoastronomical value. During the first minutes of the winter solstice -which varies between December 21 and 22-, a ray of sunlight penetrates the enclosure and touches an edge of the place, which deflects the light at the height of the eyes of an anthropomorphic figure of red color and with two small “horns” on the head. Hence the name El Diablito. This one is illuminated completely as the solar rays enter the shelter and the ray of light goes crossing the figure and other pictorial motifs from top to bottom, as the sun rises in the horizon. It is a morning phenomenon also known as a solstice marker, since it signals the beginning of winter in the northern hemisphere.
