A royal residence
After the Babenberg line ended in 1246, the castle passed to the Habsburgs. Frederick the Fair made it his residence, added a chapel and died here in 1330.
From the Hoyos family to preservation
Ludwig Gomez von Hoyos bought the estate in 1595 and restored the neglected castle. Construction of a new residence in the valley began in 1670. The older fortress gradually lost its importance and deteriorated.
Repairs continued in later centuries. Following a major collapse in 2003, preservation became particularly urgent. A phased conservation programme led by owner Ernst Hoyos began in 2013.
