In 2021 we accompanied the Municipality of Vinci in its candidature as Italian Capital of Culture 2024. In this path of strategic co-design to imagine beyond the celebratory stereotype of Leonardo and above all to design a medium-long term territorial development plan, we implemented activities of territorial research-action, community engagement, institutional and political partnership building among the main stakeholders, construction of the contents and the sustainability plan, as well as the launch of the logo and title of the candidature.
