Ahu Tongariki is the largest ahu on Rapa Nui/Easter Island (a Chilean island in the Pacific). Its moai were toppled during the island's civil wars and in the twentieth century the ahu was swept inland by a tsunami. It has since been restored and has fifteen moai including an 86 tonne moai that was the heaviest ever erected on the island. Ahu Tongariki is kilometer from Rano Raraku and Poike in the Rapa Nui National Park. All the moai here face sunset during Summer Solstice.
Moai are monolithic human figures carved from rock between the years 1250 and 1500. Nearly half are still at Rano Raraku, the main moai quarry, but hundreds were transported from there and set on stone platforms called ahu around the island's perimeter. Almost all moai have overly large heads three-fifths the size of their bodies. The moai are chiefly the living faces (aringa ora) of deified ancestors (aringa ora ata tepuna). The statues still gazed inland across their clan lands when Europeans first visited the island, but most would be cast down during later conflicts between clans.
The production and transportation of the 887 statues are considered remarkable creative and physical feats. The tallest moai erected, called Paro, was almost 10 metres (33 ft) high and weighed 82 tons; the heaviest erected was a shorter but squatter moai at Ahu Tongariki, weighing 86 tons; and one unfinished sculpture, if completed, would have been approximately 21 metres (69 ft) tall with a weight of about 270 tons.
