Chiesa dei Santi Giovanni Evangelista e Petronio

Santa Maria dell'Orazione e Morte was built in the 1730's. The Confraternità dell'Orazione e Morte (Confraternity of Prayer and Death) aims to bury anonymous corpses and pray for their salvation. In 1572 the Brotherhood acquired an area between Palazzo Farnese and the banks of the Tiber and built a small church with burial rights between 1575 and 1576. In 1732, the architect Ferdinando Fuga began to build the church that exists today, an oratory and a large cemetery, partly underground and partly on the river bank.

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.

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.
