How did the Ancients move impossibly huge objects? Why did the Roman forces at the siege of Masada decide to shift an entire mountain by hand? We reveal the ancient technology that allowed the Egyptians to move a 1,000 ton obelisk, and show how the Romans moved even heavier objects at the temples at Baalbek. As well as moving stone and earth, the ancients needed to move mountains of water, using technology we still find impressive today. Who were the most successful Mega Movers of the ancient world and how were they able to make the impossible...possible?
