The powerful Scheffel House stands in the Höllengasse. It got its name from its owner, Magnus Scheffel. He was the last overseer of the kingdom’s abbey and was the grandfather of poet Viktor von Scheffel. The poet visited his grandfather here often. Among his friends from Gengenbach were the later Director of the Karlsruhe Art Academy, the painter Hermann Götz and the musician and composer Carl Isenmann. Isenmann and Scheffel worked together a lot.
