Church of Santa Maria in Domnica

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.

The Basilica of Saints John and Paul was first erected in 398. This original church was damaged during the sack of Rome (410), then by an earthquake in 442 and was finally sacked by the Normans in 1084. The building was continually remodelled from the 11th century onwards and the building had its present appearance in 1951 when Cardinal Franz Joseph Spellman had its early Christian façade restored.

The foundations of the present church of San Gregorio al Celio were laid in the 8th century. In 1633, Cardinal Scipione Borghese had the façade rebuilt in the style of the Church of St. Louis of the French and the portico by Giovanni Battista Soria. In 1725 the interior was restored by Giuseppe Serratini and Francesco Ferrari, and in 1830 by Cardinal Giacinto Placido Zurla.
