- Bavaria is the national host with nearly 1,000 offers and a central opening in Bamberg, where more than 50 local sites and a public program mark the focal event.
- The 2026 motto "Networks: Monuments & Infrastructure" shifted attention to technical heritage such as factories, tunnels, ferries and waterworks and brought new listings into focus.
- Regions used diverse formats to engage visitors: North Rhine-Westphalia opened hundreds of sites with free tours, Baden-Württemberg highlighted unusual technical monuments, and towns like Dillingen offered guided visits to local landmarks.
- Organizers stressed that many restorations rely on mixed funding and volunteer efforts, and they said public access and apps help build local support for future preservation work.
