The Arenbergs gained prestige and wealth through iron extraction and processing, as well as through clever marriage plans, as well as through political and military activities. The castle is a nested building complex behind an elaborate courtyard façade with a farm yard in front of it, surrounded by a magnificent landscape park. The oldest part is the quarry stone residential tower of 4 storeys on the slope. In the 16th century, the tower was extended by a building to the south. Further additions in 1753 and 1807. In 1884 a further reconstruction took place: The façade was built in the style of the French. Early Baroque designed. The castle received a castle-like character with sheds, stables, utility rooms and greenhouse.
