A short walk along more medieval streets and you will reach the Cathedral of San Martino with its unusual and striking Pisa-Lucca Romanesque facade. This is where the tour ends. However, if you are not too tired, the guide will be very happy to continue the tour inside the Cathedral. There is a € 3.00 entrance fee. In the interior, the Volto Santo (the Holy Face), an evocative wooden crucifix, highly venerated for centuries and the symbol of Lucca, an incredible Last Supper painted by Tintoretto, and, in the sacristy, the beautiful marble sarcophagus of Ilaria del Carretto, the early 15th century masterpiece sculpted by Jacopo della Quercia of Siena, await your visit.
