History+
Originally, the Wilbring estate belonged to the Lords of Kunsberg or Königsberg, before passing into the possession of the von Goye family. In 1469, Diederich von der Goye sold the property to the Dortmund mayors Hengstenberg and Clepping. From approximately 1535 to 1608, Wilbring was owned by the von Westrem family. On October 29, 1608, Vincenz Rensing and Elisabeth Knippings acquired the estate for 10,400 Reichsthaler. Rensing, a Dortmund patrician and later governor of the Vest Recklinghausen, had Wilbring rebuilt in 1609. Subsequently, the estate changed hands multiple times through marriage and purchase, including the von Westerholt family (1626–1695) and the von Horst family (from 1695). From 1773 to 1856, the von Papen family were the owners.
