Schloss Harnekop, Former manor house in Harnekop, Prötzel, Germany

Schloss Harnekop was a two-story manor with thirteen windows on each main facade and distinctive mansard roofs. The building structure reflected the style of classical estate architecture from the early 18th century.

In 1772 Count Peter Friedrich Christian von Golowkin, who had received permission to settle in Prussia in 1766, commissioned a lakeside manor called Monchoix, possibly designed by Count Podewils zu Gusow. After Golowkin's death in 1787 the estate returned to the von Kameke family. In 1837 Count August Alexis Eduard von Haeseler bought it for 64,000 Reichstaler; his son, Field Marshal Gottlieb von Haeseler, died there in 1919. The Wehrmacht blew up the building in spring 1945.

The estate belonged to notable figures including Russian ambassador Count Peter Friedrich Christian von Golowkin, who named it Schloss Monchoix in 1772.

Today only minimal remains of the manor house are visible, as the structure was completely demolished around 1970. Local residents repurposed the building materials for their own construction projects.

The estate served as a training school for the SA starting in July 1932 and was briefly used by the Reich Chancellor himself in early 1945 for a military situation assessment. This episode reveals the complex role the location played during the Nazi era.
