Chiesa di Santa Maria dell'Orazione e Morte

The Church of Saints John the Evangelist and Petronius dates mainly from the 16th century when the architect Ottaviano Mascherino rebuilt the church that had been dedicated in 1582 to the patron saints of the city of Bologna. The façade is a later work from the 17th century.

The church of Santa Maria in Monserrato degli Spagnoli was built from 1518 on an old church founded by a Catalan in the 14th century. The new church was designed by the architect Antonio da Sangallo the Younger. Work was interrupted due to a lack of resources, so it was not until 1675 that the apse was completed. The church was completely restored in 1818-21 and was rededicated in 1822. Santa Maria in Monserrato is one of the national churches of Rome, this one being dedicated to the Spanish community.

The church of San Salvatore in Onda was first mentioned in a bull of Pope Honorius II in 1127. In 1445, the church and the adjoining convent were granted by Pope Eugene IV to the Friars Minor Conventual, while on 14 August 1844, Gregory XVI granted it to Vincenzo Pallotti for the religious community he had founded. After this transfer of ownership, the church, which had already undergone a radical restoration in the 18th century with the raising of the floor, was once again rebuilt by the architect Luca Carimini, who highlighted the columns and capitals of the original structure.
