Chiesa di Santa Maria in Publicolis

Sant'Ambrogio della Massima is said to have been built on the site of St. Ambrose's paternal home, where he lived (in the 4th century) until he moved to Milan as a consul. The church was rebuilt several times, but the sources do not specify the dates. In the 15th century or around 1500, it would have been joined to the adjacent church of Santo Stefano and rededicated to Saint Ambrose. Between 1606 and 1634, commissioned by the brothers Beatrice and Ludovico de Torres, one a Benedictine and the other a cardinal, it was rebuilt by Orazio Torriani and Carlo Maderno, incorporating the remains of the previous building. After 1870, the church and the monastery were expropriated by the Italian State, but later the church and part of the convent were returned to the Benedictines.

The church of Santa Caterina dei Funari is already attested in a bull of Pope Celestine III of 1192, but the present church dates back to the 16th century when Pope Paul III (1534-1549) granted it to Ignatius of Loyola. The adjoining and later convent was demolished in 1940 and the planned reconstruction was never carried out.

The Temple Maggiore was built between 1901 and 1904 on one of the four plots of land obtained through the demolition of parts of the Rome ghetto (1555-1870). In 1889, the competition organized for the design of the new synagogue saw the distinction of Vincenzo Costa and Osvaldo Armanni with building projects mixing Assyrian, Egyptian and above all Greek elements.
