Burg Rockenberg, Medieval castle in Rockenberg, Germany.

Burg Rockenberg is a castle ruin with a rectangular four-story residential tower capped by a gabled roof, flanked by three preserved round corner towers at the edges of the outer walls. The complex displays typical medieval fortified architecture with stone walls and shows the layout of a noble stronghold.

The castle was probably built at the start of the 14th century by knight Johannes von Bellersheim, who increasingly called himself von Rockenberg. Dendrochronology dates the residential tower's timber to 1317. In the early 15th century the castle was possibly extended during work on a village fortification. After several changes of owner it was abandoned as a residence by the 17th century and later served as stables and storage.

The castle serves today as a venue for local events and is maintained by the community, showing how historical buildings play a role in village life. Visitors can see how the stone walls and towers continue to shape the town's character and maintain the connection between past and present.

The former administrative building now houses a restaurant where visitors can eat and drink while exploring the grounds. It is worth checking access points and paths around the ruins beforehand, as not all areas may be open at all times.

The residential tower's construction was dated by dendrochronology to 1317. During World War II, plans for extensive underground bunkers were never carried out, but a new staircase was installed inside the tower, destroying the late Gothic castle chapel.
