24 February 2026: The approximately 1200-year-old Staufian defensive wall in the Archaeological Zone of the Imperial Palace will be restored in 2026. Preparatory work is expected to begin in mid to late April and will also affect the monument area at the Bolander Tower at the entrance to the hall area. The monument areas of the warm air heating system and the Jewish cemetery in Karolingerstraße will remain closed for safety reasons until the restoration is completed. The work is expected to be finished by the end of 2026.
All other monument areas, such as the Heidesheimer Gate and the Aula Regia, can be visited during regular opening hours. The Imperial Palace App is also available for visiting the Archaeological Zone of the Imperial Palace. It can be downloaded free of charge from Google Play and the App Store. The app is the ideal companion for a visit to the medieval palace ruins. It serves as an audio guide and digital guide, complementing the signage in the Imperial Palace area with audio texts, image galleries of historical illustrations, and digital reconstructions.
