The horror basement where sisters were raped for 41 years by their father and slowly went mad

This is the disgusting dungeon where an Austrian man violated his own daughters in a nightmare spanning 15,000 days and nights.

'If you fight back, then I will kill you,' Gottfried W. told his children Christine, 53, and Erika, 45, who were forced to sleep at night on a wooden shelf while their father, now 80, snoozed in a feather bed.

Amid farming implements, old oil drums, wood, cement sacks and filth he violated his own flesh and blood with a depravity on a par with Josef Fritzl.

His wife Berta, 85, passed away in 2008.  She too was a victim of the former council labourer's sadism, beaten like them with a stick and poked with a pitchfork. Go here if you want more information
