Open Monument Day 2025: Register contributions now

The Open Monument Day will take place in 2025 on Sunday, September 14. The motto is "Valuable-full: priceless or irreplaceable?". Registration is now open.

Every year, the Open Monument Day offers visitors a varied program on cultural heritage in the city - from Roman times to post-war monuments. The cooperation of many different stakeholders is required to make the topic of monument protection accessible to a broad public.

Take part now

Private individuals, institutions or associations that live in, use or look after a listed building in Bonn are once again invited to present it at the Open Monument Day. Interested parties can register their program items until 30 June via the  portal of the German Foundation for Monument Protection (opens in a new tab) (creation of a user account required).

Alexander Kleinschrodt from Werkstatt Baukultur Bonn (email:  denkmaltagbaukultur-bonnde is available as a contact person for participants and can help with questions about participation and registration.

The motto "Valuable: priceless or irreplaceable?" combines various intentions: It is about high-quality historical furnishings, elaborate craftsmanship and special relics that provide unique access to the past. However, it also refers to the added value that heritage conservation can offer society and the debate about what should be considered valuable and therefore worth preserving.

Further information

The motto offers local organizers many possible interpretations, but it is not mandatory to refer to it. The German Foundation for Monument Protection has compiled further suggestions at  www.tag-des-offenen-denkmals.de/motto (opens in a new tab).
