Otzberg Castle, Medieval castle in Hering, Germany

Otzberg Castle stands on the summit of the Otzberg hill in the Odenwald at 367 metres above sea level. Its appearance is defined by a double concentric wall from the 16th century and a Romanesque bergfried, locally called the Weiße Rübe, which is the oldest building on the site. The complex includes a tall gabled house, a plain white cylindrical tower and a long building with two rows of small windows.

The castle was first mentioned in 1231 and built by Fulda Abbey to secure their lands. The fortification showed the abbey's power in the region and helped protect boundaries.

The castle holds a museum with medieval weapons and documents that show how the region was fortified. Visitors can see how these objects shaped daily work and defense hundreds of years ago.

The castle is reached on foot from Hering, the village below the hill; the courtyard and bergfried were open during daylight hours before the site was closed for restoration. The surviving buildings cluster inside the oval double wall, with the Bandhaus museum and the Korporalshaus, now used as the registry office, among them.

The castle's keep is known locally as the Weiße Rübe ("White Turnip"), a name also used for the wild turnip. It is the oldest building in the castle and of Romanesque origin.
