Rano Raraku is where the moai were carved - both on the outside and inside walls of this volcanic crater on the eastern end of the island and transported all over the island to their destinations. It is estimated that nearly 900 were carved, and there are nearly 400 of them deployed, buried, or abandoned while still under construction at this site.
