Alternatively it was used as a state prison and therefore had a somewhat sinister reputation. Its prison walls have witnessed the tragic fate of many 'criminals' who spent their days there – maybe their last – under inhumane conditions, and, periodically, various highly ranked noblemen have also been imprisoned there including rulers such as Archbishop Adalbert III, arrested by his own "ministeriales" in 1198; Count Albert of Friesach (in 1253); the Styrian governor Siegmund von Dietrichstein, captured by insurgent peasants in 1525; and Prince-Archbishop Wolf Dietrich Raitenau, who died here in 1617 after six years of imprisonment.
