Schloss Fronberg, Medieval château in Schwandorf, Germany

Schloss Fronberg is a three-winged castle complex in the Fronberg district of Schwandorf, Bavaria. Its courtyard contains Renaissance arcades, and only a section of the original moat survives toward the estate yard. The building has been altered by numerous additions and renovations, making its construction history difficult to trace.

Fronberg is documented in 1305, when the castle lords were enfeoffed with the Vogtei Mappenberg to rebuild the predecessor destroyed by fire. The complex burned again during the Landshut War of Succession, and in 1594 fire destroyed almost half the village. From 1622 to 1829 it belonged to the barons von Spiering; Caroline von Holnstein, born at the castle in 1815, lived there with Wilhelm Freiherr von Künsberg. The Breidbach-Bürresheim family, owners since 1875, carried out major renovations in 1992 and 2005.

Caroline von Holnstein, born at Fronberg in 1815, lived here with her lover and later husband Wilhelm Freiherr von Künsberg; her portrait hangs in King Ludwig I's Gallery of Beauties at Nymphenburg. The castle courtyard now hosts theatre, open-air cinema and a medieval festival, and the family organizes concerts and plays for the public.

Schloss Fronberg stands in the Fronberg district of Schwandorf, southwest of the Naab, and the street leading to it is named after Randolph von Breidbach-Bürresheim, a member of the German resistance of 20 July 1944. The castle is a private residence of the Freiherren von Breidbach-Bürresheim, so visits focus on the exterior and the courtyard, where theatre, open-air cinema and a medieval festival are staged.

The street leading to the castle is named after Randolph von Breidbach-Bürresheim, a member of the German resistance circle of 20 July 1944. The family has owned the castle since 1875.
