What is the Rano Raraku quarry on Easter Island?

Rano Raraku is a volcanic crater formed of consolidated volcanic ash located on Easter Island. For about 500 years until the early eighteenth century, it served as the primary quarry where around 95% of the island's famous monolithic statues, or moai, were carved. Today, hundreds of unfinished and abandoned statues remain scattered across the site, offering a visual record of ancient design and technological innovation.
