Burg Hunolstein, Medieval castle ruins in Hunolstein, Germany

Burg Hunolstein is a castle ruin at about 395 meters elevation featuring a round corner tower and sections of original walls roughly 1.3 meters thick. The site sits on rocky terrain and incorporates natural rock formations into its overall structure.

Burg Hunolstein dates from the 12th century and was the seat of the Vögte von Hunolstein. Franz von Sickingen captured it in 1522. Damage during the Thirty Years' War led to its abandonment from 1637.

Legend makes the castle the seat of Hunold, a figure from the Nibelungen tales, while the sources record it as the historical seat of the Vögte von Hunolstein, the local bailiffs. The two traditions sit side by side: a documented administrative residence and a legendary Nibelungen hall.

The ruin stands on a quartzite rock at 395 m above sea level in the Hunolstein district of Morbach, in the Hunsrück. From the three-metre square remnant of the former keep, the view opens west into the Dhron valley and north to the Haardtkopf (658 m) near Gornhausen.

The castle was the legendary seat of the Nibelung Hunold, a figure from the Nibelungen tales. The main tower once stood on a quartzite rock; only a square wall remnant about three meters high survives, offering views west into the Dhron valley or north to the Haardtkopf (658 m) near Gornhausen.
