Chiesa di San Lorenzo in Panisperna

The church of Saints Ippolito and Lorenzo in Fonte, better known as San Lorenzo in Fonte, is said to have been built over the house of the centurion Hippolytus, where the deacon Lorenzo was held prisoner, and that he was able to baptize his jailer by miraculously causing a spring to flow, which can still be seen in the church basement. The church is first mentioned in 1348. In the 13th and 14th centuries, it was inhabited by Benedictine monks and nuns. The present church was built in 1543 at the request of the Spanish Cardinal Juan Alvarez de Toledo. In 1624, at the request of Pope Urban VIII, enlargement work was carried out by the architect Domenico Castelli, known as Fontanino.

The basilica of Santa Pudenziana dates from the 5th century, but the present basilica is largely the result of a 16th century restoration. The bell tower was added in the 13th century and a room in the left aisle was closed for construction. The restoration work completed in 1588 changed the structure of the church by demolishing the portico, removing the medieval choir and building a few pillars to reinforce the columns. Today it is the national church of the Philippines and the seat of the homonymous cardinal title.

The church of Sant'Agata dei Goti was founded in the 5th century in Rome by the Romanized Germanic general Flavius Ricimer. It is the only example of an Arian place of worship in the Roman Gothic community that has survived into the present day. The beautiful votive mosaic dating from Ricimer was lost when the church fell into ruin in the 16th century. The present Sant'Agata dei Goti, under Villa Aldobrandini, is a reconstruction of 1633 with a new façade erected in 1729.
