Sant'Eusebio all'Esquilino is an ancient monastic church dedicated to an obscure saint called St Eusebius of Rome. This church, now parochial and titular (but not a minor basilica), is at the north corner of the Piazza Vittorio Emanuele II in what is now the rione Esquilino (historically, rione Monti).

The church was financed by St Eusebius of Bologna (not St Eusebius of Vercelli), a friend of St Ambrose, and has its first historical mention in a graffito of the year 474 in the catacombs of Santi Marcellino e Pietro ad Duas Lauros. However, archeological remains hint at an original construction date of about the turn of the fifth century. This means that it is one of the oldest churches of any sort in Rome; it was also one of the tituli or first parish churches, and was known as the Titulus Eusebii certainly by 499. Later tradition alleged it was made so during the reign of Pope Liberius (352-66).
Ruins dating to ancient Roman times have been found south of the transept and behind the apse. The style of wall construction appears to date from the end of the 2nd century, and epigraphs discovered here in 1875 suggests that a sanctuary of Jupiter (Iuppiter Dolichenus) was here or nearby. The suggestion that these remains were the original house church has no archeological backing.
The church was restored around 750, before being rebuilt later that century.
It was rebuilt again and re-consecrated by Pope Gregory IX in 1238, and was granted to the Celestine congregation of reformed Benedictines (now extinct) in 1289. This had been founded in 1259 by the Italian hermit Pietro de Murrone, later Pope Celestine V. He reigned for only nine months in 1294 before resigning, and was canonized as St Peter Celestine after his successor Pope Boniface VIII almost certainly had him murdered in prison. (That he was murdered is now certain.) They built the monastery, which still exists to the right of the church and which was elevated to the dignity of an abbey in 1627.
A tablet commemorating the rebuilding may still be found in the porch of the church, to the right of the door. Around the same time, the bell-tower or campanile was added.
The church was either remodelled or rebuilt in 1711 by Carlo Stefano Fontana under the patronage of Cardinal Enrico Enríquez. There is an argument as to how much, if any, of the fabric of the 13th century church survives under the 18th century decoration. The original campanile was left alone, however.
The Celestine congregation was dispersed by the French Revolution, and was formally suppressed by order of the Napoleonic imperial government in 1810. It was not revived afterwards, but the complex was granted to the Society of Jesus. They in turn were expelled in 1873, when the monastery was seized by the state, and the future of the church was finally settled in 1889 when the parish was erected and staffed by diocesan clergy. The monastery is now occupied by the Pubblica Sicurezza.
Before the late 19th century, the church was at the far end of a little piazza next to an important road junction, but the creation of the Piazza Vittorio Emanuele has radically changed the layout of the roads in the area.
The current titular of the church is H.E. Cardinal Daniel Nicholas DiNardo.
The church has a nave with aisles, and shelters its nave and presbyterium under one pitched and tiled roof. There is no apse.
The façade dates from the 1711 remodelling and, as a result of suburban development lowering the street level, has now to be approached by steps. Despite being late 19th century, these form a pleasing mock-Palladian aspect with two transverse upper flights meeting at the top of a longitudinal lower flight. There is an internal loggia, and the first storey frontage has four gigantic Doric pilasters supporting an entablature. In between these are five arches, with their own imposts, leading into the loggia. The central one is slightly wider than the others, with its arc decorated with volutes enclosing laddering and with a scallop shell on top. It has a statue of the Madonna and Child in front of it.The second storey has five equally sized rectangular windows separated by four Ionic pilasters with swagged capitals. The pediments of the windows are treated playfully; three have ogee curves, and two are coved triangles (with inward curves). The pilasters support an entablature with a dedicatory inscription and the date, 1711. Above this is a triangular pediment with a statue of a saint at each end; one is St Eusebius and one is St Vincent, the minor patron of the church. However, the pediment is obscured by a large tympanum containing a seriously damaged coat-of-arms of Pope Clement XII. Two angels sit on top of this tympanum.
The actual entrance door to the church is flanked by a pair of marble plaques announcing indulgences offered to visitors. The older one on the right dates from the 1238 restoration, and that on the left records those conferred by Pope Gregory XIII in 1572.
The 13th century brick campanile can be seen peeping over the right hand side of the façade. It is actually at the northern corner of the monastery cloister, and is enclosed by monastic buildings. There is a tiled pyramidal cap, and each face has three soundholes formed by an arcade with each arch separated by a limestone column with a cushion capital. Examination with binoculars will reveal brown ellipses above and below the soundholes, which are the ends of tie-bars inserted to hold the structure together. Above the soundholes facing the street is also what looks like a damaged disco of verde antico, indicating that the campanile was originally decorated with polychrome stonework.
The window behind the high altar has an impressive Baroque exterior surround, which can be inspected from the Via Principe Amedeo. It is shaped like a trapezium with a curved top, and the stone frame is decorated with volutes, tassels, a scallop shell and a winged putto's head.
The adjacent monastery has a 16th century cloister, which is not on a classic square plan but is rectangular with cloister walks on two sides only. There is a fountain attributed to Domenico Fontana. The complex is now a barracks for the police forces, and can be difficult to visit. Calling at the door to the right of the church is pointless; it is best to have a contact with somebody in residence there.
The coolly decorated Baroque interior, mostly painted in a cream colour with some gilded stucco, has the arcade arches (four on each side) separated by gigantic doubled Ionic pilasters. The aisles are vaulted with shallow elliptical saucer domes. The main nave ceiling is barrel-vaulted, with transverse ribs running between the round-headed nave windows. It displays a fresco of St Eusebius in Glory by Anton Raphael Mengs of 1757.
Over the triumphal arch is the coat of arms of Cardinal Enrico Enríques, below which is a long inscription on marble carved to look like cloth and held up by two angels. The altarpiece of the high altar is a Madonna and Child by Pompeo Batoni, and that of the chapel dedicated to St Peter Celestine is by Andreas Ruthard (1630-1703).
Behind the high altar is a finely carved set of wooden choir-stalls from c. 1600, provided for the Celestine monks and apparently carved by one of them. Apparently before 1711 the choir was before the altar, instead of behind it as now.
The relics perhaps of St Eusebius of Bologna, who financed the church, are interred beneath the high altar. By tradition there are three saints here: Eusebius, Orosius and Paulinus. The latter two feature in the mediaeval romance and are certainly spurious.
The dedication of this church is a difficult one, as there is a problem as to who St Eusebius was. One tradition used to be that he was martyred with some companions in the reign of the emperor Valerian, about 255. The historical consensus now is that this martyr never existed, and so he has been deleted from the Roman martyrology. There has been confusion with St Eusebius of Vercelli, a 4th century Italian bishop famous for making his cathedral clergy live a life in common. He is counted as one of the founders of the Canons Regular -and was not a martyr. A fable was later invented that this bishop had been starved to death for supporting the Nicene creed against the Arian emperor Constantius II, but this is demonstrably false. The revised Roman martyrology (2001) has decided against identifying the church's St Eusebius with the bishop of Vercelli, and has listed the saint merely as having given his name to the church. In other words, no-one knows who he was.
The church's St Eusebius is now listed by the Roman martyrology on 14 August; St Eusebius of Vercelli has his feast-day on 2 August.
On the feast-day of St Anthony the Great of Egypt, 17 January, there is a blessing of animals in the piazza. This is an old tradition, and used to be performed in front of the church of Sant'Antonio Abate all'Esquilino until motor traffic made it dangerous in the 20th century. It used to be the case that farm animals were brought along, in the days when much of the land inside the city walls was still open farmland, and up to fairly recently horses were much in evidence. The service was so popular in the early 19th century that in 1831 the Diocese threatened priests of other churches with suspension if they copied it. Nowadays it only concerns pets, especially horrible little dogs that look like rats in platform shoes (lupe di Roma moderna, as the locals would say, the "wolves of modern Rome").
