Abandoned Engineering

S02E02 Britain's Sea Fort Complex

Off the coast of England, a peculiar collection of rusting structures emerges from the water, while a crumbling medieval-style castle sits within an American city, and a massive machine lies abandoned in a German field. Once marvels of design and engineering, these sites now stand neglected, some even hazardous. Who were the visionaries behind these enigmatic constructions? What remarkable tales do they tell? Why were they left to decay? Seven towering steel boxes rise 80 feet above the waves at the mouth of the River Thames. Known as The Red Sands Sea Fort, these relics were initially constructed to protect London from the Nazi threat, playing a vital role in the Allies' success during World War II. This episode also explores a foreboding, deserted Cold War pyramid in North Dakota, an expansive empty facility in Philadelphia, and a massive, decaying steel structure in Eastern Germany.
