Church of Santa Maria della Vittoria

The Church of Santa Susanna was founded in the 9th century but its construction lasted until 1603, when the Baroque façade was completed by Carlo Maderno. From 1587 Pope Sixtus V made the church the seat of the female Cistercian monastic community of St. Bernard. As the Cistercian community was expropriated after 1870, the church was assigned to American cardinals in 1937 and served as the national church of American Catholics until 2017. It has now returned to its original use as a Cistercian monastery.

The construction of the Basilica of Santa Maria degli Angeli e dei Martiri was entrusted by Pius IV (1560-1565) to Michelangelo, who was also working in St. Peter's Basilica at the time. The work continued after the death of Michelangelo by Giacomo Del Duca. The work continued until the middle of the 18th century when the side entrances to the transept were closed by the Chapels of San Bruno and Niccolò Albergati. With the unification of Italy, the Carthusian fathers were expelled from the church and its convent; the convent area was first left to the military, then to the friars of St. Francis of Paola and finally to the diocesan clergy. With the marriage of Vittorio Emanuele III, this basilica became a state church, a rank that it still retains today.

The Basilica of St. Camillus de Lellis was built at the request of Pope Pius X (1903-1914) on the project of the architect Tullio Passarelli. Construction began in 1906. Consecrated as a church and erected as a parish in 1910, it was entrusted to regular clerics, the Camillians. The basilica is in neo-Romanesque style with Gothic influences.
