London, May 8 : The children of incest monster Josef Fritzl will be getting their first taste of the outside world after a lifetime imprisoned underground, at a leading psychiatric clinic in Austrian woods.
The Landesklinikum clinic in Mauer, set deep within woodland, will provide Elisabeth, Stefan and Felix Fritzl with a fence from the world's attention as they are smoothly re-introduced to independence.
After years without windows, light or air, doctors say it will be at least three or four weeks before they can go out.
Doctors at the clinic say that Stefan Fritzl, 18, and his brother Felix, 5, are responding well to treatment, reports the Mirror.
They are slowly becoming accustomed to the light and their skin is getting darker, they add.
To simplify their re-introduction to the outside world, the specialists have reproduced the confined dimensions and conditions of the cellar where Josef Fritzl had kept them locked up from birth.
Doctors say that Stefan walks with a stoop as a result of years under the low ceiling of the cellar, and while Felix is able to walk he chooses to crawl.
Their mother Elisabeth, 52, is already walking around the clinic after 24 years of being imprisoned inside the dungeon where Josef repeatedly raped her and where she gave birth to seven of his children.
Doctors are also working out how best to permit Elisabeth to see her oldest daughter Kerstin, 19, who remains in a coma in an Amstetten hospital seven kilometres away.
The teenager, the first born underground, has stabilised in recent days but doctors are waiting to find out the effect of her total organ failure on her brain.
