Aggstein Castle
Perched 300 meters above the Danube River in the scenic Wachau Valley, Aggstein Castle is a formidable 12th-century ruined fortress infamous for its brutal robber barons and dark medieval legends. Most notable among its grim historical features is the 'Rosengärtlein' (Rose Garden), a narrow stone ledge protruding over a sheer cliff face where condemned prisoners were left to starve or jump to their deaths. Visitors report hearing ghostly weeping, icy winds on windless days, and phantom footsteps in the ruined keep.
