In Basel, the Gymnasium Bäumlihof once housed an intriguing piece of street art by Werner Zogg, titled "Ohne Titel," created in 1975. Located at Zu den drei Linden 80, this artwork was part of a broader initiative by Kunstkredit Basel-Stadt to integrate artistic elements into public buildings. The initiative ran from 1971 to 1976, aiming to enhance the architectural environment of nine building cores and an auditorium exterior wall.

Zogg's work, along with others from that era, faced removal due to extensive renovations after 40 years of use. These renovations were necessary to update the facilities to modern standards, but unfortunately, they impacted the preservation of many original art pieces from the 1970s. The Gymnasium Bäumlihof, which served multiple educational purposes, underwent these changes to continue serving the community effectively.

For those interested in exploring the history and visual aspects of Zogg's work, resources such as a downloadable PDF and a photo are available online. These documents provide a glimpse into the artistic landscape of Basel during the 1970s and the efforts to incorporate art into public spaces.
