Moai are statues carved from compressed volcanic ash on Rapa Nui, Chile (Easter Island). The statues are all monolithic, that is, carved in one piece. The largest moai erected, "Paro", was almost 10 metres (33 feet) high and weighed 75 tonnes (74 Imperial tons, 83 American tons). One unfinished sculpture has been found that would have been 21 metres (69 ft) tall and would have weighed about 270 tons.
