The Archeological Museum in Pienza is located inside the ex-conservatory of San Carlo, a building with medieval origins that was later extensively converted into a school.
Archeological and Etruscan collections are on display, as well as an exhibition route that documents the urban and architectural history of Pienza’s territory from Prehistory to the late-Roman period, including the formation of medieval Corsignano and its transformation into Renaissance Pienza.
The prehistoric artefacts come from the Cava Barbieri settlement, while the Etruscan objects are part of the Landi Newton collection (owned by the Opera del Duomo), with more than 500 pieces dating mostly to the Archaic Period and coming from the Borghetto necropolis in Pienza. Other artefacts (4th-3rd century BCE) come from the area around Sant'Anna in Camprena. The Roman period is documented by a residential building in the village of San Gregorio, with traces of medieval presence.
