The former Castle church of the von Venningen family stands next to Hecker's birth house. It has been owned by the artists Prof. Jürgen and Christa Görtz since 1978 and is used as an artist's studio.
The Marstall, where the castle owner's horses used to be housed, can also be seen directly at Friedrich-Hecker-Platz. After a fundamental renovation, the historic building has been used for several years as an exhibition gallery by the artist couple Görtz.
