To be privately owned
Knabenburg

The Knabenburg in Salzhemmendorf is a listed property distinguished by its historical connection to local noble families and the work of nature conservation pioneer Ernst Rudorff. In the late 19th century, he saved an old oak avenue from felling and is considered one of the founders of nature conservation in Germany.
History+
The current manor house of Knabenburg was built in 1724 during the Electorate of Hanover. The associated farm buildings were constructed later, one in 1812 during the French period and another in 1840 during the Kingdom of Hanover. A staircase was added in 1840 to connect the buildings. The name “Knabenburg” derives from the term “Homburger Knaben,” which referred to members of the knighthood in the lower Börde of the Eschershausen office. The property frequently changed hands, including many noble families and, after the Thirty Years' War, also bourgeois families. An episode occurred in 1886 when the composer Ernst Rudorff, who used Knabenburg as a summer residence, bought a centuries-old oak avenue to save it from felling – an early civil society nature conservation action.
