The Wolfsburg (Catholic Academy, Mülheim an der Ruhr)

The Wolfsburg in Mülheim an der Ruhr is a Catholic academy, a house for adult education and social education of the diocese of Essen.The building, designed in the local style with strong Art Nouveau elements, was built in 1906 as the summer residence of the Böllert brewery family from Duisburg. For a short time, the facility was used as an alternative site for the Raffelberg brine bath, which was able to open later than expected due to construction delays. The name is based on the last wolf shot in the area, which is why the hill on which the Wolfsburg stands is called Wolfsberg. For decades, the Wolfsburg was a popular place for excursions in the Speldorf forest for guests from the area, especially since you could ride up from the Ruhr on donkeys.During the Second World War, the administration of the 4th Flak Division was located in the Wolfsburg building from about May 1942 to April 1945.[1] After the war, the large house served as quarters for British officers.In the early 1990s, the Wolfsburg was completely renovated and converted into today's modern conference venue. The listed facades were preserved, the Art Nouveau windows were faithfully reproduced.

A beautiful building plus outbuildings, a few steps around it is really worth it.

<< History of Wolfsburg >>
"... In the vicinity of the Ruhr - in the middle of one of the largest industrial cultural landscapes in Europe - the WOLFSBURG is located in an extensive forest area.
Built in 1906 in Art Nouveau style, it served as a spa and forest hotel for the Raffelberg saltwater bath in Mülheim an der Ruhr. The unusual sounding name WOLFSBURG is a reminder that wolves lived in the surrounding forests until the beginning of the 19th century.The detailed history of the architecture and development of the academy:
