CSOA Forte Prenestino is a large self-managed social centre based in a squatted fort in Centocelle, Rome. It was occupied on May Day 1986. Forte Prenestino is an "important node of production of cultural and political events" and hosts many groups and events across its 13 hectares.

Self-managed social centres in Italy exist in many cities. They are part of different left-wing political networks including anarchist, communist, socialist, and autonomist. The centres tend to be squatted and provide self-organised, self-financing spaces for alternative and noncommercial activities such as concerts, exhibitions, farmers' markets, infoshops, and migrant initiatives. Over time, some but not all projects have opted to legalize their status.
