Among the many chapels, the Chapel of the Cross certainly stands out. It contains frescoes, recently restored, by Amico Aspertini (1508-1509). The blue vault shows us God surrounded by angels, prophets and sibyls. Above the altar is an anonymous 17th-century painting representing "Volto Santo, St. Augustine and St. Ubaldo". On the right wall is the fresco of St. Frediano displacing the course of the river Serchio, while trying to stop the flooding. Next to it is a column which is, at closer sight, actually flat. The sgraffiti are drawn in the art technique of trompe l’oeil, giving a false perspective and the illusion of a column. On the left wall is the fresco of the "Transportation of the Volto Santo from the port of Luni to Lucca by the Blessed Giovanni, bishop of Lucca". In the front the stooping old lady in red robe certainly steals the show. The mortal remains of this bishop are preserved in this chapel.
