Today, the Baroque Kossenblatt Castle stands on the site of a medieval moated castle. Field Marshall and Minister Count J.A. Von Barfus had the castle built from 1699 to 1712. However, the Field Marshal died before the castle was finished, and his wife, the former Eleonore Countess von Dönhoff, had the work completed. Theodor Fontane recorded many of the tales about the family and their wealth. King Frederick William I acquired the castle in 1736 as a home for his old age, but only stayed there a few months before his death in 1740. In the years that followed, ownership of the castle changed frequently, and the castle was finally restored in 1967. The castle is currently in private ownership.
