Murder Raid Tunnels

Exploring the forgotten underworld hiding beneath the streets of Cincinnati, USA. Late 19th Century Cincinnati was a hub of German immigrants who introduced lager to the United States. To make their beer they needed cool temperatures, so they headed underground.

Also, a state-of-the-art Cold War fortress on the shores of Denmark. These dark tunnels were once the first line of defence for NATO in their battle against Russia and her allies. The clifftop guns above the caverns packed enough firepower to hold the Russian Baltic fleet while reinforcements arrived.

And, there's a deep dive into the tunnels spanning the Mersey River in Liverpool. Driven by the rise of the automobile and increasingly clogged ferry routes, the Queensway Tunnel was both a feat of engineering and a world first when it opened in 1934.

For centuries, people have built mind-blowing structures underground. This new series explores the incredible places and spaces beneath our feet.

Underground Worlds reveals the hidden stories of some of the world's most extraordinary underground structures, both natural and man-made, brought to life with spectacular visuals and expert investigation and explanation.

We are taken on a journey across the world, and beneath it, to see just what man and Mother Nature have created out of sight. We visit the largest and most spectacular cave networks ever discovered, gain access to vast operational subterranean complexes, explore forgotten man-made tunnels and venture into mothballed military bunkers.

Each episode features three underground worlds and unpacks each unique story - its conception, its construction, its uses and, in many cases, its repurposing for different future uses.
