Schloss Bellinghoven, Water castle in Haffen, Rees, Germany.

Schloss Bellinghoven is a moated castle six kilometres south-east of Rees, in a former bend of the Rhine between the Haffen and Mehr districts. Its roots lie in a motte: an artificially raised mound with a wooden tower, a moat and a palisade. Stone buildings replaced it over time, and after destruction in 1598 the main parts were rebuilt in castle form and altered again in the 17th century.

The castle was first documented in 1325, when Dietrich von Bellinghoven, who had completed its construction, enfeoffed it to Count Dietrich VII of Kleve, making it an open house of the counts. In 1598 Spanish troops took it on their third assault, plundered it and killed its inhabitants; Konrad von Bernsau then rebuilt the main parts as a castle. In 1788 the preacher Johann Gottfried von Manger bought it and gave it its present form.

The name Bellinghoven comes from the noble family first recorded in 1206 with Gerard von Bellinghoven. Under the Reformed owner Wilhelm von Bernsau, the local Protestant congregation was allowed to hold services in the castle every 14 days; this ended after his death under his Catholic son-in-law. Since 1983 the Caritasverband Oberhausen has run a remedial-education facility here for young adults with mental impairments, so the grounds are not open to visitors.

The castle is located at the edge of Rees and can be reached via Bellinghovener Strasse, making for straightforward access to the grounds. Visitors should be aware that the property functions as a therapeutic facility today, so respectful conduct around the grounds is important during any visit.

During the 1974–1976 renovation, medieval pottery shards and bone remains were found in the castle courtyard. The site had passed from the mining company Walsum to the Catholic youth organisation in Duisburg-Hamborn, which gave it free of charge to the association "Die Brücke" in 1974.
