Geoglyphs, on the Pampa de Nazca, depicting two human figures wearing headdresses and standing on opposite slopes, facing different directions and holding an object in each hand. They are presumably images of a deity that probably date back to between the 4th and 1st Century BCE when the Paracas culture waned and the Nazca culture dawned. Many geometric ground drawings were created by the pre-Inca Nazca culture in Southern Peru. These giant geoglyphs are now a UNESCO World Heritage Site.
