KAIRÓS is an URBACT Action Planning Network focused on cultural heritage as a driver for sustainable urban development and regeneration. In ancient Greek KAIRÓS means the propitious moment, and this is the moment to test an innovative policy framework, combining a sound integrated approach with a real transformation purpose. To meet this challenge, the KAIRÓS model pursues the proper assemblage of five key dimensions, namely: space, economy, social accessibility, attractiveness and governance.
