Seven concrete-based monuments, a clear representation of European CH, have been chosen as case studies to validate the performance of the proposed solutions. They have been selected according to scientific and humanistic criteria and because they will be used to study economic and societal effects of the proposals and to promote citizens’ awareness of 20th Century European heritage. Thus, the selection includes monuments with significant numbers of visitors per year, such as the spectacular Centennial Hall building, included in the UNESCO world heritage list and Chillida sculptures. In addition, other buildings and sites that are hardly recognised by citizens as Cultural Heritage, such as Concrete Shell Structures, an important achievement of the post-war modernist movement, and War Memorial Towers, symbols of the collective identity of European citizens, have also selected. Finally, the Torroja Building has been chosen as a representative model of interdisciplinary collaboration between architecture and engineering during the 20th Century.
