Saint Stephen' s church is mentioned in the second half of the XIII century. it was restored during the XVI and XVII centuries and, than, during the XVIII and XIX centuries.
Inside there are the statues of Saint Lodovico from Tolosa and Saint Anthony Abbot, much prized sculptures in terracotta realized by the Buglioni's workshop (see the Hospital of Ceppo in Pistoia). Here Saint Lodovico from Tolosa holds in his hand the little model of the village because, according to an ancient legend, he saved it in 1306, after the siege by the forces of Moroello Malaspina.
In the Saint Stephen' s square the medieval siege of 1302 is commemorated : here some actors act a historic process during the Medieval Festival every year.

The statue of Saint Lodovico, saint patron of the village, is made of plaster and papier-maché. Since XVII century it has been carried in procession every 19nt August, during the patronal day. The procession winds along the streets of the castle and along Saint Lodovico street, so called since XVII century: in 1631 the statue was carried in procession to protect the inhabitants against the plague.

At the early XIX century a fine pipe organ, made by the famous Pistoian workshop of Agati, renewed the interest for the ancient church. It even now makes eighteenth-century timbres.
