Torhaus von der InnenseiteIllustration für_ Eugen Zeller, Aus sieben Jahrhunderten der Geschichte Beuggens, Wernigerode_ Gottlieb Koezle, [1921], S. 366 1920

"Torhaus von der Innenseite" is a 1920 pen and ink drawing by German artist Otto Ubbelohde, depicting a gatehouse viewed from inside the walls of an old European town. The detailed depiction of the building's architecture, its surrounding greenery, and the two figures in the foreground showcases Ubbelohde's mastery of the medium. The illustration likely served as a book illustration for the 1921 work "Aus sieben Jahrhunderten der Geschichte Beuggens," by Eugen Zeller. The artwork is currently housed in the Städel Museum.
