The aim of the project is to develop an innovative, collaborative and circular systemic approach for regeneration and adaptive reuse of historic city centers. This will be implemented by implementing a repertoire of successful heritage-led regeneration initiatives. The project tests the replicability of the spatial approach and of successful models addressing the specific needs of historic city centres. ROCK delivers new ways to access and experience Cultural Heritage, ensuring environmentally-sound solutions, city branding, bottom-up participation via living labs, while increasing liveability and safety in the involved areas. Sensors and tools support the concrete application of ROCK principles and the platform will enable new ways to collect and exchange data to facilitate networking and synergies.
