Austrian Gottfried Wagner is accused of keeping his own daughters captive and raping them for 41-years, and now RadarOnline.com has horrifying new details of the lair where he allegedly committed his torture.

The police charge that Wagner's daughters Christine, 53 and Erika, 45 were forced to live in squalor amid farming implements, oil drums and cement sacks while their own father lived in luxury in the rest of the house which he kept pristine.

The women - who are now mentally ill after the years of alleged abuse - had to use a commode in the middle of the room and slept on a wooden shelf instead of a bed, according to The Express newspaper of Great Britain and Germany's Bild.

While police are grilling the 80-year-old over the sickening abuse which spanned 15,000 days and nights, more details are being uncovered.

The women have told the police that they and their mother, Berta - who died in 2008 -  were all victims of Wagner who they say beat them with a stick and poked them with a pitchfork.

Police claim he beat them all into submission and made his daughter's promise on their mother's deathbed not to tell anyone what he had done.

He also warned them during his frequent sexual attacks: "If you fight back, then I will kill you."

Neighbors in the village of St Peter am Hart described the former council laborer - who they knew as Freidl - as a 'stern and rigid' master of his house.

The forty-one years of alleged abuse only ended in May when Christine snapped during an attack and hit her father over the head with a milk jug.

He lay injured on the floor for two days before the sisters finally raised the alarm and an ambulance took him to hospital.

It was another month before they opened up about the torment.

The case eerily mirrors that of Josef Fritzl, another Austrian, who was given a life sentence for rape, incest, enslavement, and false imprisonment of his daughter Elizabeth after locking her in the basement and fathering seven children with her.

Nurses treating their mother visited the home of two sisters for a decade, apparently unaware that the women were allegedly being caged, raped and tortured by their father.

The revelation is shockingly similar to what occurred at the home of Phillip Garrido, who held kidnap victim Jaycee Dugard captive at his California home for 18 years, even while probation officers -- he was a registered sex offender -- regularly visited his property.

In the case of Gottfried Wagner, the 80-year-old Austrian man who has been arrested for raping and torturing his two mentally challenged daughters for a stunning 41 years, nurses visited the home regularly from 1998 to 2008 to care for Wagner's ailing wife Berta. Berta was also allegedly raped and brutalized by her husband.

Following Berta's death, yet another nurse, a specialist in disability issues, visited the home several times because one of the daughters was having trouble walking, reports The Sunday Herald.

Neighbors of the house of torture in the tiny Austrian town of St Peter am Hart, most famously known as the birthplace of Adolph Hitler, have said they never noticed anything unusual at the property, although it was nicknamed by locals as The Witches House.

Christine Wagner, 53, and Erika Wagner, 42, are now in residential care and being given psychiatric treatment.

Their father has reportedly denied the allegations against him.
