Chiesa di San Gregorio della Divina Pietà
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.
