Documented since 1081,the church looks like a fortified body, with the typical features of the Sienese 13th-14th century military architecture; on one side, is situated the Church. On this side, made of brick, like most of the complex, but with rows of stone in the simple façade, has a single nave with trusses in sight. Inside are visible traces of a fourteenth-century fresco with St. Christopher and of another fresco, fragmented, too, where we can see the figure of the Blessed Franco da Grotti
