Stonehenge is a prehistoric monument, erected around 2200 BC. But how it was constructed remains a mystery. There are a number of theories, but little hard evidence.

A possible answer has come from an unlikely place. Wally Wallington found a way to move massive weights by himself. He does it without modern tools.

Wallington plans to erect a Stonehenge in his backyard. In this Video of the Day, stands a 19,000-pound pillar on end. It’s impressive.
