This article deals with the governance of common goods within regeneration projects of UNESCO heritage sites. The main objective is to evaluate the existence of conditions that prove the con-temporary function of common goods as drivers of strategic regeneration of complex territories with high cultural value. The research identifies some of the strategic planning policies implemented for the historical centre of Naples and analyses their proactive function in the enhancement, conser-vation and reuse of built commons. The expected result is to contribute to the debate on the cultural planning of the territory, aimed at the diversification of services and the fight against the process of touristisation. Through desk research and consultation of primary sources, a brief outline is given of the historical process that led to the birth of the "Great UNESCO Project" in the historical centre of Naples. The paper then analyses the "Discipline of the common goods - Principles for the govern-ance and management of the commons in the city of Naples", defining its addresses, opportunities and limitations as a contribution to relational, oriented and sustainable strategic territorial planning.
