The Schönberg estates belonged to the cathedral chapter of Marienwerder, which was headed by a provost named Schönberg. The castle was built between 1301 and 1386 on the banks of the Haussee to secure the estate. More information at: https://de.wikipedia.org/wiki/Burg_Sch%C3%B6nberg_(Ostpreu%C3%9Fen)
