After the poet Joseph Victor von Scheffel (see 25) ascended to the noble class, he acquired the Mettnau estate in 1876 and expanded the old tenant house into a castle. A tower was added to the old building where the poet set up his study. Today the health resort administration of METTNAU is located here. Some editions of Scheffel's works are on hallway display. However, due to official use, there is only limited visitor access to the building.
