After welcoming remarks by Mayor Gertrud Maltz-Schwarzfischer and Dr. Michael Schmidt (Bayerisches Landesamt für Denkmalpflege), Prof. Dr. Ursula Schädler-Saub and Prof. Dr. Thomas Danzl reported on the history of restoration in Regensburg. The interdisciplinary insiTUMlab team of the Chair of Conservation-Restoration, Art Technology and Conservation Science at the Technical University of Munich showed how combining research in conservation-restoration with analytical investigation (imaging and punctual methods) allows new insights into the four painting phases in the chapel (12th–17th centuries) and their material composition, in front of a general and expert audience.
On Tag des offenen Denkmals®, the chapel, which is otherwise closed to the public, opened its doors: around 70 visitors were able to experience the four painting phases live, search for fragmentary faces, and learn about the analytical methods used to reveal hidden layers and characterize lapis lazuli and fluorite, among others.
The project results provide a reliable data basis for future conservation interventions and presentation concepts for the fragmentary wall paintings and enable well-founded art-historical interpretations for the first time. The colloquium thus marks the step from research to practical application: better understood layer by layer, more protected step by step.
