Oberhof Ballenstedt, Late Gothic stately home in Ballenstedt, Germany

Oberhof Ballenstedt is a Late Gothic three-winged schloss next to the town hall in the southern old town of Ballenstedt. Groin vaults from the construction period survive on the ground floor, and a connecting wing between the west and east wings was inserted in the 19th century. The building began as a fortified town castle of the lords of Stammern.

The Oberhof was built in the 16th century as a fortified town castle (Stadtburg) held in fief by its builders, the lords of Stammern; their 16th-century gravestones and epitaphs are kept in Ballenstedt's St. Nicholas' Church. It later passed to the von Krosigk family and in 1825 to the ducal house of Anhalt-Bernburg. A single connecting passage between the west and east wings was inserted in the 19th century. In 1869 Armgard von Alvensleben acquired the property and laid out a 15,000 m² park.

The name Oberhof denotes the principal farmstead of a lord, combining residence, administration and economy in one complex. The 15,000 m² park laid out by Armgard von Alvensleben in 1869 belongs to the estate, and since 2010 the owners have opened the building for cultural events, earning the Denkmalpreis of Saxony-Anhalt in 2023.

The day care centre that occupied the building from 1948 was closed in 2002, and the Oberhof is once again owned by the von Alvensleben family. Renovation began in 2010, supported with 30,000 euros from the Deutsche Stiftung Denkmalschutz, covering the roof structure, facades, the decorative gables and the interior. The owners now open the property for cultural events.

The Oberhof was a fortified town castle before becoming a schloss, and its 16th-century builders, the lords of Stammern, are still present in Ballenstedt: their gravestones and epitaphs are kept in St. Nicholas' Church. The property passed to the von Krosigk family and in 1825 to the ducal house of Anhalt-Bernburg.
