Burg Katzenstein bei Frickingen 

Karl Ballenberger's "Burg Katzenstein bei Frickingen" is a detailed pencil drawing of a medieval castle perched atop a rocky outcrop. This piece, characteristic of Ballenberger's romantic and picturesque style, highlights the architectural grandeur of the Burg Katzenstein, capturing its imposing presence against a subtle background. The soft tones and meticulous detailing of the castle structure, nestled amongst rocky formations, evoke a sense of history and the enduring power of these ancient fortifications. The work provides a glimpse into Ballenberger's fascination with the history of his homeland and its architectural treasures.
