The ceremonial village of 'Orongo is one of the most fascinating and important sites on Easter Island. Located at the top of Rano Kau's precipitous cliffs, 'Orongo offers awe-inspiring views toward the three off-shore islets of Motu Kao Kao, Motu Iti, and Motu Nui. The village consists of about fifty dry-laid stone buildings (referred to by numbers according to Ferdon 1961: Fig.13 7), and occupied seasonally during the famous Birdman competition (Routledge 1920:426, Metraux 1940:331-332). The houses are usually overlapping, which probably simplified their construction.
