The islanders call this stone platform "Ahu" ( Ahu), and the stone statue sitting on the stone platform is called "Moai". Among them, there are five stone statues sitting on the largest stone platform. They are of different sizes, and some of them are incomplete. There is a stone statue sitting on each of the other two stone platforms.
