Bieberstein Castle is located on the left bank of the river Bobritzsch in Bieberstein, part of Reinsberg municipality, in Landkreis Mittelsachsen, Saxony.
A nobleman Günther von Bieberstein who named himself after the castle was first mentioned in a document of 1218. A bergfried with square footprint reminds of the medieval castle which was later transformed into an early modern castle. The latter was joined to the medieval bergfried into a contiguous building around 1600.
