Abandoned Engineering - Ghost.Ships

Some of the world’s most amazing engineering projects and buildings now lie in ruins. But how and why? In this episode we hear about some once-great triumphs of marine engineering, now left to rust. A ship graveyard in Maryland has been colonised by wildlife. And we go inside a Cold War sub.

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