Altenhof Castle in Upper Austria's Rohrbach district dates to 1204, making it one of the region's oldest structures. The castle is notable for housing Austria's largest castle church and commanding a terraced position 600 meters above the Rannatal valley, three kilometers north of the Danube. Reconstructed after a 1724 fire and owned by the Salburg family since 1602, Schloss Altenhof now offers holiday apartments and serves as a venue for weddings, celebrations, and seminars, with internal visits available by appointment.
