They were once some of the most advanced structures and facilities on the planet, standing at the cutting-edge of design and construction. Today they are abandoned, dangerous, some of them even deadly. From uninhabited cities to empty factories, these long-forgotten engineering marvels are scattered around the globe. Science Channel uncovers why some of the world's most advanced architectural achievements were eventually left behind in the all-new series Mysteries of the Abandoned.
Some of the world's most incredible engineering projects are now deserted; an ambitious Nazi project that met a sinister end in the Czech Republic; a Cold War relic in Rochester, England that changed history; a cutting-edge research complex built by visionary genius Nikola Tesla; and a research station in the California mountains.
A strange Cuban prison, an eerie escape route for Los Angeles, California built for Armageddon, a dam in Italy, and an underwater marvel near Dover, England that changed history are mysterious deserted engineering projects, and new discoveries reveal how they were built and why they were abandoned. The Season 2 premiere.
