Italy, Slovenia, Germany, Poland, Croatia, Czech Republic and Hungary within 3-year project “FORGET HERITAGE” will reply to the question: How to improve capacities of the public and private sector for the sustainable use of cultural heritage and resources in Central Europe? Most cities are characterized by the presence of unused historical buildings (former factories, hospitals, schools, barracks) that have marked the history of the local community. Now, in a state of neglect, their historical memory is being forgotten and they have a negative impact on the surrounding areas by turning into "urban voids". "New ideas need old buildings" (Jane Jacobs): the challenge jointly tackled by the project partners is to find an innovative and sustainable solution for the protection and valorisation of the Central Europe cultural heritage, increasing its economic value. The main project objective is to promote cooperation among partners’ cities in order to identify innovative, replicable and sustainable Private Public Cooperation management models of the abandoned historical sites (recognised as cultural heritage) by valorising them through setting up cultural and creative companies. The consortium aims to provide recommendations for other cities how to enhance the hidden potential of the cultural heritage to influence the quality of life of the citizens and cultural creative industries operators who will have new working opportunities and boost their managerial skills. Further results are: Management Manual, Transnational Training Model and within Pilot Actions Ex-Ante Assessment and Ex-Post Evaluation. The project will also develop tools to indicate buildings in underutilised areas ideal for cultural and creative use. Transnational cooperation allows to find novel solutions. Collective results to influence national policies, develop human resources and strengthen local managerial systems are the added value of this collaboration. Forgetting to remember, remembering to forget?
