The Church of San Giovanni Battista was built from 1282 to 1307. The layout of the church consists of three naves. The black and white marble striped façade is of a Ligurian/Pisan gothic style and is quite charming. The main portal is surmounted by a fresco portraying Saint John baptizing Christ. Worth mentioning is the elegant rose window, attributed to Matteo and Pietro Campiglio. Of great interest inside the church is a triptych portraying the Virgin and Child between two saints. This painting is unsigned but attributed to the school of Giotto. The square medieval bell tower is crowned with battlements and double Gothic style arches on each of the four sides. The bell tower was originally built in the Middle Ages as a watchtower.
