It’s something we never think about in our daily lives – but beneath our feet there’s a whole other world. It ranges from meandering tunnels to massive caverns to whole cities, an astonishing variety of underground constructions that prove that there’s more to our planet than meets the eye.
Some of what lurks below we know about – but there’s a lot more that we don’t. Some we were never meant to discover, never meant to see. Some projects are so ancient that even now we don’t fully understand their purpose. And some are so secret that few people know they’re there. All are extraordinary works of engineering, sometimes breathtaking in scale. Why were they made, and how? This series goes deep underground, in search of the hidden side of our history.
We go across the globe to uncover everything from smugglers’ tunnels to underground towns complete with transport systems and factories; from ancient caves and catacombs to the most modern technological marvels; and from natural wonders to groundbreaking scientific experiments.
We dig deep into their construction, discover the stories behind them and talk to some of the people who work and even live underground.
