Next, the app guides you to the Historische Schlossmühle, the historic castle mill located at the lake’s edge. Its waterwheel, once used to grind grain for the castle estate, now serves as a picturesque reminder of living history.

The tour concludes at the Gottesbuden, a row of medieval almshouses built in the 17th century to shelter the poor, offering a quietly poignant example of early social responsibility.
