This HD video documentary reveals how Easter Island's Moai statues were constructed by experimenting with ancient engineering methods and mysterious traditions, modern archaeological scientists and engineers try and recreate and decipher their secrets. The statues are carved stone human figures with over-sized heads, often resting on massive rock platforms called ahus buried underground. There are 1,000 statues that exist on the island, 30 feet tall, weighing a colossal 75 tons and are scattered about the barren landscape, in the mountains and close to the ocean. Society and tradition was tribal and a primitive culture, with black magic religious priests, chieftains writing strange hieroglyphic writing languages known as rongorongo. Yet this culture built monolithic statues not unlike Europe's Stonehenge. Without modern equipment, how were they built and moved?
