"Empty buildings and infrastructures are full of the echoes of real people and vanished lives, leaving many questions unanswered and mysteries unsolved. We explore the worlds strangest engineering projects that created empty silent cities. We ask why a ruined cold war air base has become a no-go area and how a tiny Japanese mining island become the most over-crowded place on the planet. We find out if the street layout of the Soviet Union's model city become a matter of life or death for its population. And how did Nazi Germany create a huge mind control facility at a holiday resort?"

"We aim for the stars and find out why unwanted battleship guns allow the United States to gain vital information about the borders of space. We ask how the shattered remains of a secret Nazi base became the first on the path to a new world, with the development of the ground-breaking V2 rocket. We explore a forgotten structure deep in the Arizona desert to ask if it is the true home of America's space programme. And we reveal the bizarre link between a discarded oil drum and a Cold War struggle to survive in zero gravity."

"Soaring across some of the widest rivers and deepest valleys on the planet, bridges have always been at the cutting edge of engineering. We travel high into the mountains of the Colorado desert to find out why a hidden engineering masterpiece could disappear at any time. We ask why a stretch of overgrown concrete in a Czech reservoir is known as 'Hitler's bridge'. We find out how the highest bridge in the world collapsed in less than one minute. Finally, we uncover the story behind Cape Town's invisible bridge, which never carried a single vehicle."

"Exploring ship graveyards, including Scapa Flow in Orkney, where German warships were scuttled after the First World War, and Mallows Bay, home to 200 wrecks colonised by wildlife."

"Hear how a crumbling hill in the Peak District and dunes in California caused the closure of two roads. Learn why a route used by the French Resistance shut in 2003."

"A dark past explains why the P\u00f6litz Synthetic Fuel Plant in Northern Poland is now a derelict industrial site littered with tunnels, bunkers and huge crumbling concrete structures lost in dense forest. The site was built in 1937 as part of Nazi Germany's drive to become self-sufficient on fuel, but it was no ordinary refinery. It used the latest technology at the time, at great expense, to turn coal into oil. In 1945 an Allied air raid pulverised the plant, severely wounding the German war machine and leaving the site in ruins.\n\nOther structures examined in the first episode include the incredible vertical Phoenix Shot Tower in Baltimore, which was built to provide America's own ammunition, the former American spy instillation called Teufelsberg (or \"Devil's Mountain\") in Berlin which waged the Cold War against the Soviet Union, and the now derelict Rubjerg Knude Lighthouse which was built on Europe's second-fastest moving sand dune in Denmark."

"A strange group of rusting structures off the coast of England, a dilapidated mediaeval-style castle in the heart of urban America and one of the biggest machines ever built lying forgotten in a German field. Once these extraordinary places and objects were at the cutting edge of design and construction, but now they stand disused, sometimes contaminated and sometimes dangerous. But who was it that built these mysterious structures? What incredible stories surround them? What secrets do they hold? And why were they abandoned?\n\nSeven huge steel boxes rise 80-feet out of the water off the coast of England at the mouth of the River Thames. Now rusting and derelict, The Red Sands Sea Fort was originally built as a first line of defence to deter the Nazi threat to London. Successfully helping the Allies to victory in 1945, the project is one of the most extraordinary engineering successes of World War II.\n\nAlso in this episode, a sinister-looking deserted Cold War concrete pyramid in North Dakota; a vast empty complex located in the heart of a Philadelphia; and a 4,000-tonne corroding mass of steel, left to rot in a field in Eastern Germany."
