Motte Aldeberg, Motte (tower mound castle) in Wegberg, Germany

Motte Aldeberg is a medieval castle complex near Wegberg featuring an extensive outer defense structure positioned on a promontory. The ruins overlook the wetland areas surrounding Helpenstein creek in North Rhine-Westphalia.

Built in the late 12th century, the castle served as an administrative center for regional affairs and horse breeding operations. It was abandoned in the early 15th century as these functions declined.

The site appears in local folklore connected to supernatural beings and ritual practices that continue to shape how people understand and experience the place today. These stories form part of the cultural memory of the surrounding communities.

The site sits along several hiking routes, including a loop trail from Büch and another from Arsbeck passing through protected nature areas. Wear sturdy footwear since the terrain is uneven and paths traverse wetland sections.

The castle was a knight's fief held by a "miles de orsbeke"; its lord, knight Stephanus, left the site right after the lost Battle of Worringen. The abandoned "old castle" later fed werewolf and Heinzelmännchen tales and a cult of intercession with binding-magic customs, prompting a local priest to build a chapel in the 19th century, demolished in the 1970s.
