In Bergen op Zoom came EFFORTS with Liberation Route Europe and FORTE CULTURA to discuss the role of fortresses in the Second World War. Fortresses were often used as concentration camps and prisons during the Second World War or were the scene of heavy warfare. Many of these sites are now memorials and offer exhibitions to commemorate this period. Due to their orientation, both cultural routes can reflect on this topic together. The project approach under discussion is intended to reappraise the Second World War in fortress monuments and realise it for tourism. Fortress sites with a corresponding history are invited to participate in the project.
