In Old Cairo, within the Roman fortress of Babylon, the Church of Saints Sergius and Bacchus, known as Abu Serga, is dated by some tourism sources to the 4th-5th century. The more solidly sourced academic account, drawn from Wikipedia, attributes the present structure to the late 7th century, the work of the scribe Athanasius under the Umayyad governor Abd al-Aziz ibn Marwan. The building burned in a fire in Fustat around 750, under the reign of Marwan II, and was rebuilt in the 8th century, with further work through the medieval period.
According to a long-standing Coptic tradition — not a historically verified fact, but a deeply held religious belief — the crypt beneath the high altar is where the Holy Family is said to have rested during the flight into Egypt to escape Herod. This crypt also gives the church its other name, the Church of the Cave. Some scholars, however, date the crypt’s actual architecture to the 12th-13th century, later than the tradition’s own setting.
The crypt, roughly ten metres below the altar, has historically suffered flooding from rising Nile groundwater. Direct descent was closed and replaced with a glass viewing panel. It is unclear from the most recent sources whether modern engineering has permanently resolved the problem, so accessibility should be checked at the time of the visit.
For centuries, from Patriarch Isaac (681-692) to Patriarch Christodulus (1047-1077), the church was the traditional site for the enthronement of the Coptic Patriarchs of Alexandria.
In basilica style, with a central nave and two side aisles, the church has marble columns — according to some sources partly reused from earlier buildings, though without rigorous archaeological confirmation — a wooden iconostasis inlaid with ivory, and three altars dedicated respectively to Saints Sergius and Bacchus, Saint George, and the Virgin Mary. The dedication recalls the two Roman soldier-saints Sergius and Bacchus, originally from Syria, who were martyred for their Christian faith according to hagiographic tradition, commonly placed under the persecutions of Emperor Maximian.
The church remains active today under the Coptic Orthodox Diocese of Old Cairo, Manial and Fum al-Khalig. It is open daily with no entrance fee, and forms part of the Coptic Cairo complex alongside the Hanging Church and the Ben Ezra Synagogue.

History
Abu Serga’s centuries-long role as the traditional enthronement site for Coptic patriarchs placed it at the institutional heart of Egyptian Christianity for nearly four hundred years, a status distinct from, though reinforced by, its older devotional association with the Holy Family’s flight into Egypt. The gap scholars identify between the tradition’s ancient setting and the crypt’s later medieval architecture is a reminder that a site’s spiritual significance and its physical fabric often developed on different timelines.
