Note: Deserted village atop Rano Kao, Easter Island. It comprised stone houses with roof vaults built as false arches. These houses and contiguous circular masonry dwellings with roof entrances are characteristic of the early and middle periods on the island; while unknown elsewhere in Polynesia, such structures are common in the adjacent area of South America. Formerly was the center of the birdman cult; site of many petroglyphs of tangata manu (birdmen) and other images.
