Church of San Giovanni Calibita

The Basilica of San Bartolomeo all'Isola was built around the year 1000 to house the relics of the apostle Saint Bartholomew. The Basilica of St. Bartholomew is today the place of commemoration of the "new martyrs" of the twentieth century: to mention just a few examples, the basilica celebrates Bishop Óscar Arnulfo Romero and Cardinal Juan Jesús Posadas Ocampo, killed by drug traffickers, the evangelical pastor Paul Schneider and farmer Franz Jägerstätter, opponents of Nazism.

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 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.
