The parish church of San Pietro was built in the 12th century but extensively restored during the 19th century, when its structure was reduced to a single nave.
Its walls still show the remains of the three-nave design with pillars and a bell tower distinguished by double and single mullioned windows. Its rather plain façade is preceded by a 16th-century loggia supported by four
columns. A central rose window belongs to the same period, while the coats-of-arms of the Cavalcanti family and of Santa Maria Nuova date from the previous century.
Inserted in the church’s central altar is an ancient relief carving from the 12th century depicting Saint Peter and two magnificent Annunciations, attributed to Ghirlandaio’s son, Ridolfo, and to Francesco Curradi, a 17th-century Florentine painter. Of great interest is the tabernacle made of grey stone dating from the 14th century.
Originally, the bell tower was probably a defensive structure. The Blessed Giovanni delle Celle was imprisoned here in the 14th century.
