Rethwischhof Manor

In 1442, the knight Hermann von Wyersrode was the owner of the place, which later belonged to Mathias von Ratlow and subsequently passed into ecclesiastical possession. The Lübeck church sold Rethwisch to the Ratzeburg Abbey, which after a short time resold it to Sievert von Heest. Rethwisch remained in the possession of the von Heest family for about 100 years until Anna von Heest sold it in 1616 for 70,000 Thalers to Duke Johann the Younger of Schleswig-Holstein-Sonderburg. From then on, the place was temporarily a duchy. Johann the Younger of Holstein-Sonderburg bequeathed Rethwisch in 1662 to his son Duke Johann of Schleswig-Holstein-Plön. He left the place to his sister Eleonore, who built a half-timbered manor house in a meadow depression. After her death, the property returned to her brother, who bequeathed it to his son Duke Joachim Ernst of Holstein-Rethwisch. He had the manor house built by Eleonore demolished and constructed a stone castle. The castle, completed in 1699, was demolished in 1785, after the estate was converted in 1729 by Duke Johann Adolf Ernst into a ducal Plön office, which fell to the Danish King Frederick V in 1761.

When serfdom was abolished in 1773, the Rethwisch estate was divided into parcels. The current manor house is located on the former outwork of the ducal castle and was built in 1780.
