Legend has it that the founder of the parish was San Frediano, bishop of Lucca in the 6th century. The church, starting from the 11th century, took the name of Plebes de Fosciana.
Inside the building you can admire various works of art, starting with an Annunciation by Andrea Della Robbia, paintings by the school of the Lucca artist Pietro Paolini, by Antonio Consetti from Modena. The sacristy of the sixteenth century is also interesting. There is also a 14th century baptismal font.
