For many years it has been supposed that the inland moai of Easter Island were simply those giant monoliths that did not make it to the coast.  Either too heavy to move further or broken by the arduous journey using pulleys, they were simply abandoned.

A new team of academics from the United Kingdom have come up with an alternative suggestion – and perhaps the moai are finally to give up their last secret. The monoliths, it is now argued, played a pivotal role in the island’s road system and were left in their places much more specifically than the old consensus ever suggested.
