Moai or moʻai are monolithic human figures carved by the Rapa Nui people on Rapa Nui in eastern Polynesia 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, which account for three-eighths of the size of the whole statue. They also have no legs. The moai are chiefly the living faces of deified ancestors.

Ahu Akivi is a particular sacred place on the Chilean island of Rapa Nui, looking out towards the Pacific Ocean. The site has seven moai, all of equal shape and size, and is also known as a celestial observatory that was set up around the 16th century. The site is located inland, rather than along the coast. Moai statues were considered by the early people of Rapa Nui as their ancestors or Tupuna that were believed to be the reincarnation of important kings or leaders of their clans. The Moais were erected to protect and bring prosperity to their clan and village.
