Set on a small hill not far from Campagnatico is the village of Montorsaio.
Standing on a high forest-covered plain formerly
rich in mineral veins, the castle, mentioned as far back as the 12th century, belonged to local families.
Until 1375 the Salimbeni family exercised strong control over this territory but were eventually forced to yield to Siena's jurisdiction.
The medieval walls are still recognisable today composed of two concentrical oval-shaped circuits. Most of the walls however have been incorporated in the present buildings. Of medieval origin and largely restructured is the parish Church of San Cerbone and San Michele, Note that in the early years of the 14h century a group of followers of Fra' Dolcino, judged heretics,
were put to death in the convent.
The remains of the Castello di Stertignano, which belonged to the Aldobrandeschi family, can be explored at a spot called "Marrucheti".
Large areas of the castle walls remain with a rustic building inside which has been extensively restructured.
