Overview
- The Tag des offenen Denkmals takes place on Sunday, 13 September 2026, when organizers coordinated by the Deutsche Stiftung Denkmalschutz will open over 6,500 registered monuments across Germany.
- This year’s motto, „NetzWERKE: Denkmale & Infrastruktur“, directs attention to sites tied to connections and services such as rail lines, power plants, bridges and post offices.
- The national opening is in Bamberg, Bavaria lists nearly 1,000 local offers, and the programme includes large city events alongside small rural sites.
- Regional tallies published by authorities show 689 participating objects in Saxony, about 350 in Rheinland‑Pfalz and roughly 260 in Mecklenburg‑Vorpommern, with many more listings in other states.
- Local organisers are running guided tours, restoration demonstrations, museum openings and hands‑on workshops this weekend, which organizers say helps boost public support, volunteer activity and local cultural tourism.
