Wikipedia says about the house:
Haus Ruhr is a noble residence in the district of Bösensell in the municipality of Senden in the Coesfeld district.
The core of the rectangular mansion dates from the 16th and 17th centuries and was given its current appearance in 1742 as a result of a renovation by the Westphalian baroque master builder Johann Conrad Schlaun. The side wing adapted in style is an addition from 1905–1907. The house is surrounded by a moat. In the northeast corner, a small island is divided off by another ditch.
In 1295 a family from Offerhues is named, who had the house from the Lords of Lüdinghausen as a fief. Around 1376 the house was in the hands of the von Hamme family as an episcopal fief. The Münster hereditary families Voss and von Belholt followed later. In the 15th and 16th centuries, the property was in the hands of the Lords of Tilbeck until 1585 when the heiress Gertrud von Tilbeck brought it into her marriage to Burkhard von der Ruhr. In 1703, the von und zur Mühlen family bought Haus Ruhr, which has been running the estate to this day.
The house houses a large archive of documents and writings as well as a valuable collection of books by the Vredener canon Jodocus Hermann Nünning. Younger than the castle is the neo-Gothic chapel from 1873 in its current form.
