The unimpressive house, 40 Ybbsstrasse, Amstetten, Austria home of Josef Fritzel and his wife Rosemarie. It was behind these walls in the cellar below that Fritzel imprisoned his daughter Elisabeth, raped and gave her three children while his other three children lived normally above them with their mother. Elisabeth reportedly used to tell her children in the cellar, Kerstin, Stefan, 18, and Felix, five, that "heaven was upstairs" - PICTURE BY JOHN McLELLAN
