Chiesa di San Leone I

The Church of Saints Fabiano and Venanzio was built in 1936 by the architect Clemente Busiri Vici. The interior consists of a nave and two aisles; the presbytery is crowned by a mosaic covering the entire wall, representing Christ blessing with Saints Fabian and Venantius. In the church premises, there are works from the former church of Saints Venantius and Ansovino, demolished in 1928 for the construction of the Piazza di San Marco.

The basilica of Santa Croce in Gerusalemme was built from the 4th century to preserve part of the cross of Jesus. After its collapse due to abandonment, the church was restored by Pope Lucius II (1144-1145). On this occasion it was given a Romanesque appearance, with three naves, a bell tower and a porch. The church was modified again in the 16th century, but it received its present Baroque appearance under Pope Benedict XIV (1740-1758), who had been the titular of the basilica before its elevation to the papacy.

Santa Maria della Misericordia al Verano is a church located in the huge municipal cemetery of Campo di Verano. The cemetery of Campo di Verano was originally founded by Napoleon's French invaders, who issued an edict in 1804 banning the ancient burial practices in the city. Having not evolved since the Middle Ages, they were rightly considered too unhealthy. Pope Pius IX (1846-1878) commissioned Virginio Vespignani to design the cemetery and oversee the construction of the main architectural elements. The church was completed in 1862.
