Church of San Giovanni a Porta Latina

The Basilica of San Sisto vecchio was first built in the 4th century and rebuilt at the beginning of the 13th century by order of Pope Innocent III (1198-1216). A fresco painted on this occasion and depicting scenes from the New Testament and apocrypha is preserved. The rest of the building, with the exception of the apse and the bell tower, was rebuilt in the 18th century by order of Pope Benedict XIII (1724-1730).

The Basilica of Santo Stefano Rotondo al Celio was founded by Pope Simplicius between 468 and 483 and is dedicated to Saint Stephen, a martyr whose body had been found a few decades earlier in the Holy Land and transported to Rome. The church was embellished by Popes John I and Felix IV in the 6th century. In 1130, Innocent II added three transverse arches to support the dome. In 1454, Pope Nicholas V entrusted the ruined church to the care of the Hungarian Pauline Fathers. The church was restored by Bernardo Rossellino. In 1579, the Hungarian Jesuits took over from the Pauline Fathers.

A first church was built here in antiquity, mentioned in the acts of the synod of Pope Simmaco in 499. Pope Paschal I (817-824) had the basilica rebuilt in 818-822, endowing it with mosaics. The appearance of the present church of Santa Maria in Domnica, however, owes much to a reconstruction in the 16th century, when the church was closely linked to the Medici family.
