In 1629, Stružnice was bought by Vilém Wratislaw of Mitrovice, Grand Prior of Knights Hospitaller.

He annexed it to the Horní Libchava estate and tried to transfer the property to the Wratislaw of Mitrovice family, but it remained in the possession of the Knights Hospitaller order until the first half of the 20th century.
