Itinerary A

[3] The decorations of the aisles

the walls of the aisles, still unfinished pending a mosaic decoration which was never carried out, were designed and embellished, according to 18th-century style, with the insertion of a number of chapels with wall decorations consisting of friezes, pilasters, frames and stucco sculptures of classical inspiration. As a result, the aisles were covered by a barrel vault with lunettes, concealing the original roof.
