The church of San Pietro in Montorio was built from 1481 to 1500 on the place where ancient sacred buildings honoured St. Peter, who was allegedly crucified here. Due to its position on the border of the town, the complex suffered serious damage at the hands of the French of Napoleon III, who intervened in 1849. In 1876, the building was ceded by the Italian State to Spain and served as the seat of the Royal Academy of Spain in Rome.
The church of Santa Maria delle Grazie alle Fornaci dates back to the XV century, but it was rebuilt at the end of the XVII century with drawings by Francesco Multò. In 1720 Filippo Raguzzini added the façade and it was not until 1950 that the bell tower was inserted.
The Basilica of S. Maria in Trastevere, is supposedly the first official place of Christian worship built in Rome and certainly the first dedicated to the cult of the Virgin. According to the legend, the church was built in 340 on the oratory founded by Pope Callixtus I in the 3rd century, when Christianity had not yet spread.
