The debate on sustainable development often overlooks urban issues and Built Heritage. However, historic centers are the areas where global challenges become evident in all their complexity. A shift in perspective is both urgent and necessary. It involves viewing urban cultural heritage and its communities not just as a problem but as part of the solution. Integrating historic preservation into development plans assigns an active role to this heritage in project strategies. This chapter encourages reflection on the importance and prioritization of this legacy by highlighting key challenges and introducing methodological tools for addressing them.
