Leaving Valdicastello, you head along the Sarzanese State Road which leads from Pietrasanta to Lucca. Go towards Camaiore where you should stop in piazza San Bernardino to see the Collegiata of Santa Maria Assunta.
Outside the residential area of Camiaore, along the ancient via Francigena, you will find the Abbey of San Pietro, the only remnant of the ancient Benedectine monastery which was built here ca. 760 CE (you can still see the door of the original monastery, which today offers access to the Sacristy.) The present-day structure, however, has more recent origins. It was founded in the 12th century and restored at the end of the 19th century after earthquakes. Take time to see the tabernacle and the font of holy water inside.
From Camaiore, continue along SP 1 towards Pieve di Camaiore-Lucca: the road will begin to climb and will become increasingly winding before you arrive at Montemagno. Continue to climb until you arrive at the intersection for Gualdo – Pieve a Elici – Massarosa. Turn right here and continue for about 5km in the direction of Massarosa, passing the crossing for Gualdo until you arrive at Pieve a Elici where you should stop to visit the romanesque Parish Church of San Pantaleone. This church is linked to the evangelical missions of Saint Frediano, Bishop of Lucca at the end of the 5th and beginning of the 6th centuries CE.
