This paper focuses on a very original and peculiar peacebuilding experience - the Peace Laboratory of Magdalena Medio. Based on the civil society and located in a highly conflictual region of Colombia, it represents a peacebuilding from below initiative with the political and financial support of the European Union. The Peace Laboratory seeks new paths to peace and development and an alternative model of peacebuilding, in a country which desperately needs new and imaginative solutions and formulas to peace.Above all, what is at stake is to question if the Peace Laboratory is a real peace laboratory and where is it heading for.
