About thirty-five kilometers southeast of Siena rose one of the hermitages that contributed to the birth of the new Order of the Hermit Friars of Saint Augustine in Tuscany between 1244 and 1250. It was founded between 1256 and 1259 on an earlier hermitage called San Pietro a Camerata. The convent became famous for the presence of a friar, Antonio da Siena, whose life is wrapped in legends that a reliable identification very difficult. However, it seems certain that he died in 1311 in Monticiano. His body was first placed under the side altar of the church and later put in a glass case above the high altar. Despite the friars’ great devotion to the saint, which attracted the faithful in great numbers, Monticiano remained a small village. Like the one at Rosia, this monastery never joined the congregation of Lecceto and in 1808, as a result of Napoleon’s edicts, it was suppressed.
