The earliest church was consecrated by Pope Simplicius between 468 and 483. It was dedicated to the protomartyr Saint Stephen, whose body had been discovered a few decades before in the Holy Land, and brought to Rome. The church was the first in Rome to have a circular plan, inspired by the Church of the Holy Sepulchre in Jerusalem. Santo Stefano was probably financed by the wealthy Valerius family, whose estates covered large parts of the Caelian Hill. Their villa stood nearby, on the site of the present-day Hospital of San Giovanni - Addolorata. St Melania the Elder, a member of the family, was a frequent pilgrim to Jerusalem and died there, so the family had connections to the Holy Land.

The church was originally commissioned by Pope Leo I (440-461), with the date confirmed by ancient coins and by dendrochronology, which places the wood used in the beams of the roof to around 455 AD, but was not consecrated until after his death. The original church had three concentric ambulatories flanked by 22 Ionic columns, surrounding the central circular space surmounted by a tambour (22 m high and 22 m wide). There were 22 windows in the tambour but most of them were walled up in the 15th century restoration. The central ambulatory had a diameter of 42 meters, and the outer one a diameter of 66 meters. Four side chapels extended from the middle ambulatory to the outer ambulatory, forming a Greek cross.

The church was embellished by Pope John I and Pope Felix IV in the 6th century with mosaics and colored marble. The church was restored in 1139-1143 by Pope Innocent II, who abandoned the outer ambulatory, and three of the four side chapels. He also had three transversal arches added to support the dome, enclosed the columns of the central ambulatory with brick to form the new outer wall, and walled up 14 of the windows in the drum.

In the Middle Ages, Santo Stefano Rotondo was in the charge of the Canons of San Giovanni in Laterano, but as time went on it fell unto disrepair. In the middle of the 15th century Flavio Biondo praised the marble columns, marble covered walls and cosmatesque works-of-art of the church, but he added that unfortunately "nowadays Santo Stefano Rotondo has no roof". Blondus claimed that the church was built on the remains of an ancient Temple of Faunus. Excavations in 1969 to 1975 revealed that the building was actually never converted from a pagan temple but was always a church, erected under Constantine I in the first half of the 4th century.

In 1454, Pope Nicholas V entrusted the ruined church to the Pauline Fathers, the only Catholic Order founded by Hungarians. This is the reason why Santo Stefano Rotondo later became the unofficial church of the Hungarians in Rome. The church was restored by Bernardo Rossellino, it is presumed under the guidance of Leon Battista Alberti.

In 1579, the Hungarian Jesuits followed the Pauline Fathers. The Collegium Hungaricum, established here by István Arator that year, was soon merged with the Collegium Germanicum in 1580, which became the Collegium Germanicum et Hungaricum, because very few Hungarian students were able to travel to Rome from the Turkish-occupied Kingdom of Hungary.

The Cardinal Priest of the Titulus S. Stephani in Coelio Monte has been Friedrich Wetter since 1985. His predecessor József Mindszenty was famous as the persecuted Catholic leader of Hungary under the Communist dictatorship.

Reconstruction of the appearance of the church in the 5th century.


Although the inside is circular, the exterior is on a cruciform plan.

The walls of the church are decorated with numerous frescoes, including those of Niccolò Circignani (Niccolò Pomarancio) and Antonio Tempesta portraying 34 scenes of martyrdom, commissioned by Gregory XIII in the 16th century. Each painting has a titulus or inscription explaining the scene and giving the name of the emperor who ordered the execution, as well as a quotation from the Bible.

Works of art

The altar was made by the Florentine artist Bernardo Rossellino in the 15th century. The painting in the apse shows Christ between two martyrs. An ancient chair of Pope Gregory the Great from around 580 AD is preserved here.

The Chapel of Ss. Primo e Feliciano has very interesting and rare mosaics from the 7th century. One of them shows the martyrs Primus and Felician flanking a crux gemmata (jewelled cross). The chapel was built by Pope Theodore I who brought here the relics of the martyrs and buried them (together with the remains of his father).

Hungarian Chapel

Unlike nationals of other European nations, Hungarians lacked a national church in Rome, because the old Santo Stefano degli Ungheresi in the Vatican was pulled down to make way for the sacristy of the St Peter's Basilica in 1778. As a compensation for the loss of the ancient church, Pope Pius VI built a Hungarian chapel in Santo Stefano Rotondo according to the plans of Pietro Camporesi.

The Hungarian chapel is dedicated to King Stephen I of Hungary, Szent István, the canonized first king of the Magyars. The feast of St Stephen is held on 20 August. Hungarian pilgrims frequently visit the place.

Hungarian experts took part in the ongoing restoration and archeological exploration of the church during the 20th century together with German and Italian colleagues. Notable Hungarian visitors were Vilmos Fraknói, Frigyes Riedl, and László Cs. Szabó, who all wrote about the history and importance of Santo Stefano.

Recent archeological explorations revealed the late-antique floor of the church in the chapel. The floor is composed of coloured marble slabs and was restored in 2006 by an international team led by Zsuzsanna Wierdl.

The frescoes of the chapel were painted in 1776 but older strata of paintings were recently discovered under them.


Archdeacon János Lászai, canon of Gyulafehérvár, was buried in the Santo Stefano Rotondo in 1523. Lászai left Hungary and moved to Rome where he became a papal confessor. His burial monument is an interesting example of Renaissance funeral sculpture. The inscription says: "Roma est patria omnium" (Rome is everybody's fatherland).

There is a tablet recording the burial here of the Irish king Donnchad mac Briain, son of Brian Bóruma and King of Munster, who died in Rome in 1064.


Under the church there is a 2nd-century mithraeum, related to the presence of the barracks of Roman soldiers in the neighbourhood. The cult of Mithras was especially popular among soldiers. The remains of Castra Peregrinorum, the barracks of the peregrini, officials detached for special service to the capital from the provincial armies, were found right under Santo Stefano Rotondo. The mithraeum belonged to Castra Peregrinorum but it was probably also attended by the soldiers of Cohors V Vigilum, whose barracks stood nearby on the other side of Via della Navicella.

The mithraeum is currently being excavated. The remains of the Roman military barracks (from the Severan Age) and the mithraeum under the church remain closed to the public. A coloured marble bas-relief, "Mithras slaying the bull" from the 3rd century is today in Museo Nazionale Romano.

List of Cardinal Priests of the church

The titulus S. Stephani in Coelio Monte was cited for the first time in the Roman synod of 499.
