Another important and singular manifestation in the rapa Nui culture is the rock Art that was developed through two modalities: petroglifos and paintings.
In the island exist around 1,000 sites of Rock Art with approximately 5,000 registered motives, that are grouped in 12 groups emphasizing the anthropomorphous figures and isolated anthropomorphous characteristics, birds, species, ceremonial objects, boats have settled down, etc.
The main motive in the petroglifos is the representation of the man bird or Tangata Manu. It is engraving on rocks of Mata Ngarau in the ceremonial village of Orongo next to volcano Rano Kau. The paintings are littler in the island, being in places like Motu Nui (one of small barren islands in front of Orongo), in inner walls of some houses of Orongo, in the Ana Kai Tangata cavern and other caverns located in the North coast.
