The hit documentary series that explores some of the world's most mysterious abandoned structures returns for an all-new second series.

Once these structures were among the most advanced engineering projects ever undertaken, but now they lie ruined, disused, and sometimes deadly. Each episode of this fascinating and fast-paced series uncovers the stories behind their rise and fall and asks 'who built them? And why? And why were they abandoned?'
