The feudal ownership on the site of the present Myllendonk Castle was first mentioned in the annals of 1166. The ancient castle standing on the site successively belonged to different noble families. Among them is the noble house of the Dukes de Croy. A representative of this dynasty was one of the first field marshals of the Russian Empire under Peter I. From de Croy the Castle, in turn, passed on to the Counts Ostein and remained their ownership until the reform of the feudal structure of Europe in 1814. After that, Myllendonk Castle became the property of the Kingdom of Prussia.
Most of the extant buildings date to the XVII century. In the XIX century the castle often attracted painters. Comparing the images of the castle in those times to its current appearance, it's easy to make sure it has not changed. There is an elite golf club and a restaurant in Myllendonk Castle now.
