The famous giant stone heads located on Easter Island are called Moai. Created by the Rapa Nui people between the 13th and 16th centuries, these monumental statues are primarily carved from volcanic tuff and represent ancestor figures, embodying the spiritual and ancestral beliefs of the island's inhabitants. Moai stand on stone platforms known as Ahu, which serve as graves for important leaders. There are nearly 900 of these statues scattered across the island, making them a significant archaeological and cultural landmark that attracts researchers and tourists alike.
