The Bishop of Lucca, saint Frediano performed in the 6C the miracle of holding back the capricicious waters of Serchio. This is certainly how the story goes in the frecoes in this Romanesque church's chapel of Saint Agostino which was built partially with materials recovered from the amphitheatre. . This church is dedicate to story-telling, since a sculpted baptismal basin charts the episodes of Moses, whilst the large Byzantine style mosaic deals with the 'Ascension.
