The M.A.M. (Monteriggioni Archaeological Museum) is located in the monumental complex of Abbadia Isola, undergoing progressive restoration and becoming a new cultural hub in the area.

The museum is outdoor-indoor, meaning it aims to tell the history of the abbey through specific panels and open-air enhancement elements, while the two exhibition areas (La tinaia and sala Sigerico) narrate the events of the Monteriggioni territory through reconstructions, models, multimedia supports, artifacts, and panels in a journey back in time, from the Middle Ages to prehistory.

It is a museum in progress, intended to be enriched over time with rotations of exhibited artifacts; furthermore, it is dedicated to ongoing educational activities and research in the area.
