After the earthquake in 1703, the inside of the church was completely rebuilt in Baroque style by three great architects of that period: Cipriani, Contini and Biarigioni. In 1724 Ferdinando Mosca made the magnificent wooden ceiling which was painted by Girolamo Cenatiempo, who was also the painter of frescos in the chapel hosting the saint's mausoleum. In 1773 Donato Rocco completed the principal altar.
