The architectural heritage value is recognized today internationally. Its safeguarding contributes to territories attractiveness and their development. Portugal and Romania affirm their will to preserve this heritage. Nevertheless, in the field, the practices often contradict this will. Day after day, it is the prey of not enough qualified professionals who contribute to its degradation. Its permanent maintenance is however a practice which, controlled well, can contribute to territories revalorization and environment safeguarding. Project PRO-EXEMPLARIA proposes to work out training devices for maintenance of built heritage and to train Portuguese and Romanian trainers who will put them into practice. These devices concern above all professionals of construction companies and employees of local authorities, which are directly concerned by this topic in their daily professional activity. These devices, short modules of training meeting the professionals needs as well as possible, will be developed on the basis of transfer of methodological and teaching tools designed by Ecole d’Avignon. Preliminary studies on Romanian and Portuguese built heritage will be used as a support for their development. Trainers will be recruited in each country to be formed on these devices during pilot training courses. In parallel will be undertaken a study on a process of access to a qualification “Built Heritage” for building companies thanks to the training of their employees. In the long term, one will be able to observe an improvement of the qualifications and aptitudes of professionals intervening on built heritage in Romania and Portugal. The quality of works realized on built heritage will feel the effects of it. Territories, becoming more attractive, will draw from it the resources of their development.
