The view through the basement windows of Ariel Castro's 'house of horrors' is obscured by an impenetrable triple-layer of razor wire, tinted perspex and chicken fencing.
But newly released footage provides a chilling snapshot of the murky dungeon lair in which the Cleveland kidnapper held three women captive for over ten years - and where he fathered a child with one of them.
Perhaps more disturbing, however, is the array of child's play things, including a pink Barbie bike hanging from a rafter and a basketball hoop, strewn around his backyard.
Surrounded by a high wall of tarpaulin sheeting to hide the garden from neighbours' eyes, this was the only place Michelle Knight, Amanda Berry and Gina DeJesus could see the sky for roughly a decade until their dramatic escape earlier this month.

The film, released by CNN, also shows spools of barbed wired tossed about his backyard alongside heavy metal chains and rolls of tarp that he used to hide his neighbour's view and an array of children's toys which were likely used by the daughter he fathered with one of his captives.
Police have sealed the scene as they continue to search for clues inside the Seymour Avenue home in west Cleveland, but the images show that Castro did much of the blocking off himself.
While police were the ones to replace the back door with a piece of fresh plywood, Castro had taken out the windows from the back of the house and completely blocked them with gray wood to keep any neighbors from looking into his home.
