Secrets of Lost Empires (#2403)

Located in the Salisbury plains of England, Stonehenge has been clouded in mystery for centuries. Only recently have archaeologists been able to glimpse into its ancient history. Built at the end of the Stone Age some 4,500 years ago by a sophisticated civilization, Stonehenge was a remarkable feat of technology. As archaeologists attempt to duplicate the ancient temple, they encounter difficulties such as how to transport a 40-ton stone 22 miles across the hilly British terrain without the aid of modern technology.
