In the 18th century the property belonged to von Delvig [de] family. From 1783 to 1825 it was property of the family of Magnus Johann Scotus (ennobled in 1788 in Vienna as Scotus von Scott) and his daughter Johanna (Jeanette). The manor was sold to Dr. Wilhelm Johann Engelbrecht von Zoeckell and later became the property of Luise von Zoeckell and her husband baronet Gottlieb von Fersen. The manor belonged to von Fersen family until World War I.

In 1922, the Guard House was established in the manor house. After World War II there was a school (until 1969), the local collective farm used the castle cellars for warehouses.
