Santi Sergio e Bacco degli Ucraini

Santi Sergio e Bacco is a Catholic church of the Byzantine Rite in the rione of Monti in Rome, Italy, located in Piazza Madonna dei Monti. Saints Sergius and Bacchus are said to have been early fourth-century Roman military officers and Christian martyrs buried in Syria. In the 9th century the church was known as Sergius and Bacchus in Callinico, in the Middle Ages as Sergius and Bacchus de Suburra, and from the 18th century has been known as the church of Madonna del Pascolo.

Since 1970 it has been a national church of the Ukrainian Greek Catholic Church in Rome and is now known officially as the "Parish of Ukrainian Catholics of Madonna del Pascolo and Saints Sergius and Bacchus."

The Liber Pontificalis attests four institutes in Rome by the ninth century dedicated to Sts. Sergius and Bacchus, such was the popularity of these saints, though sometimes unclearly as to which one is meant:

The first unambiguous references to the predecessor of the church in Monti are to an "oratory of Sts. Sergius and Bacchus which is located in Callinico," to which Pope Leo III (795‑816) gave gifts (LP 98.24, 98.78), and the "monastery of Christ’s holy martyrs Sergius and Bacchus called Callinicum" to which Pope Benedict III (855‑858) gave silver gifts including two chalices, a paten and incense boat (LP 106.26). Callinicum is a city in Syria. The ninth century monastery was under the authority of St. Paul’s Outside the Walls.

In the eleventh century the monastery was populated by Benedictine monks, known in the Catalogue of Turin as the "Church of St. Sergius in Suburra."Suburra is an ancient and modern name of the neighborhood.
