The next chapel on the right-hand side was originally built in the 15th century at the commission of Cardinal Lorenzo Cibo de'Mari, nephew of Pope Innocent VIII, and dedicated to St Lawrence. The chapel was completely rebuilt by Carlo Fontana between 1682 and 1687 for Cardinal Alderano Cibo (1613-1700) to glorify the achievements of his family, the dukes of Massa and princes of Carrara. The entrance arch of the chapel was decorated by the ducal arms of the Cybo Malaspina dynasty made of polychrome marble. The barrel-vaulted vestibule is enclosed by a black marble balustrade.
