Volcan Rano Raraku is the open-sky quarry where the ancient Rapa Nui used to carve out their Moai (statues).
Rano Raraku contains numerous now empty niches where statues have been hacked out, as well as 397 figures visible on the outer and inner slopes illustrating every phase of the carving process. Among the unfinished statues is "El Gigante", with a height of 22 meters and weighing 165 tons.
