Basilica of San Bartolomeo all'Isola

The church of San Giovanni Calibita was founded in 1584 on an ancient church mentioned as early as the 11th century. The 16th-century church was renovated in 1640, the façade was completed in 1711 and the interior in 1742. The rich interior decoration is the work of Corrado Giaquinto.

San Gregorio della Divina Pietà is a small church first mentioned in 1403. In 1729 the church was restored according to the plans of Filippo Barigioni, commissioned by Pope Benedict XIII Orsini di Gravina and entrusted to the Congregation of the Workers of the Divine Piety, hence its name. In 1858 the church was restored and a bilingual Hebrew and Latin inscription with a passage from the Bible was placed on the façade. The church is famous for the compulsory sermons that were imposed on Jews during the papal reign.

The Basilica of San Nicola in Carcere was consecrated in the 11th century and partially rebuilt in the 16th century, on the site of an earlier church. The church is dedicated to St. Nicholas because of the Greek population in the area. In the 11th century, it was known as the church of Leonis Petrus, in reference to a Jewish family, converted, who turned the nearby theatre of Marcellus into a fortress. The basilica was rebuilt in 1599, with a new façade by Giacomo della Porta. The medieval tower and bell tower, abandoned at the time, have been preserved.
