Barbican 

This simple pencil drawing by Karl Ballenberger depicts a Barbican, a fortified gateway, a common feature in medieval architecture. The artist, active in the early 19th century, captured the structure’s austere beauty through subtle lines and shading. The drawing highlights the architectural details of the Barbican, showcasing its arched entrance and the surrounding walls. The absence of color emphasizes the structure's form and creates a sense of timeless grandeur. This artwork, housed in the Städel Museum, provides a glimpse into the architectural history of a bygone era.
