On the outskirts of the city of Salisbury, England, there's a pretty unassuming series of rolling fields that stretch as far as the eye can see.

Aside from a few grazing sheep, there's nothing much here, except jutting out of one of these fields is a bizarre monument that dates back some 5,000 years.

This is Stonehenge, one of the last remaining relics of England's mysterious ancient past.

It's a monument that consists of an outer ring of 13-foot-tall Sarsen standing stones,

weighing around 25 tons, the equivalent of a large

fire truck. Each, and the smaller blue stones in the middle aren't actually that much smaller

weighing between two and five tons, which is still a couple of cars worth of rock.

But here's the thing.

5,000 years ago, there was no heavy machinery like cranes or excavators.

There's no other structures nearby or big trees that could have been used for leverage.

So these had to have been lifted into place by hand.

But how?

It was a question that had historians scratching their heads for decades.

That was until one man set out to solve this problem, in his backyard.

And as he was doing so, he made a shocking discovery, one that would change how we understood ancient engineering forever.

Intrigued?

Well, grab your hard hats, because we're going to take a look at the secrets he uncovered, along with even more ancient engineering marvels.

You're listening.

You're listening to be amazed. marvels.

Now, Stonehenge is located on the Salisbury Plain in Wiltshire, England. However, the man who channeled his efforts into recreating it in his own

backyard lives across the pond in Lepere County, Michigan. Meet Wallace T. Wallington,

a former construction worker with one heck of a name who became massively obsessed with
