"...This huge Moai, or the living faces of deified ancestors, was carved between 1100–1680 AD and there are 887 of these stone statues across Easter Island, a small spot off the Chilean coast line.
The faces were carved by the Rapa Nui people, and most of them sit exactly where they were created, near the the extinct volcano Rano Raraku.
While most of the Moai are where they were carved, a small percentage of the statues were moved to where they sit now. Each face represents the deceased head of a lineage and they’re carved
using stone hand chisels while being splashed with water in order to soften the stone..." - History Daily
