Hollenburg Castle was constructed in the 12th century by Lord of
Hollenburg on the Northern side of the Drava river valley. It was
first mentioned in 1142 deed dedicated to foundation of Viktring
Abbey. Hollenburg Castle sits on top of a rock cliff at 561 meters
(1,841 feet) above sea level. Original
medieval Hollenburg Castle was badly damaged in 1348 during Friuli
earthquake. However it was quickly restored. A year later in 1349
Hollenburg Castle became registered as the seat of a land judge.
Emperor Maximilian I sold the castle to Siegmund von Dietrichstein
in 1514. Dietrichstein family greatly increased the size of
Hollenburg Castle in the 16th and 17th century to its present
House of Dietrichstein rebuilt Hollenburg Castle in a
Renaissance style and owned until 1861 when the family finally died
out. It was acquired in 1913 by the Wittgenstein family that still
holds possession of the citadel. Hollenburg Castle is a private
property hence it is closed to the public.
