The pandemic, with its environmental and socio-economic crises, has highlighted the urgency of structural responses. Overcoming this polycrisis requires the reactivation of a community and identity dimension of places. Cultural institutions can play an important role in this process. This paper proposes a focus on the role of ecomuseums in the creation of resilient communities, able to renew themselves to respond to crises. The ecomuseum movement is strongly committed to the eco-social transition of communities and territories and offers good practices for the management of common goods, methods and tools for the recognition of local identities, joint decision-making, co-planning, the care of living cultural heritage, the integral development of the landscape and the monitoring of impacts.
