Pushing 14 Tons of Concrete

Exactly how the Moai were moved across the Easter Island has been ages long mystery. There have been numerous theories about the same. A simple one of them is that the statues could not have been moved without human labor and required minimum the help of ropes among other things. Another simplistic theory is that logs were used to roll the Moai to the desired location. If these theories were to be thought of practically then each structure would have required a labor of 50-100 people to move.
