The two identical chapels opening in the right transept are relatively insignificant in terms of artistic value in comparison with the other side chapels of the church. Both were built during Bernini's intervention in the 17th century but their present decoration is much later. The most significant work of art is the fragmented sepulchral monument of Odoardo Cicada, the Bishop of Sagona by Guglielmo della Porta which is dated around 1545. The tomb, which was originally bigger and more ornate, is located in the Cicada (or Saint Rita) Chapel.
