Seven Saints Church, the Black Mosque turned Orthodox church in Sofia
Seven Saints Church (Sveti Sedmochislenitsi) is a Bulgarian Orthodox church in the centre of Sofia, set in a small garden near the Count Ignatiev School. It began in the sixteenth century as the Black Mosque and was rebuilt as a church that was consecrated in 1903. It is a rare place where Roman, Ottoman and Bulgarian layers of the capital meet in one building.
This Orthodox church in the heart of Sofia was an Ottoman mosque, then a military warehouse and a prison. Beneath it lie an early Christian church and a Roman temple of Asclepius.
The history of Seven Saints Church
The ground under this church has been sacred for a very long time. Excavations in 1901 uncovered the remains of an early Christian church dating from roughly the fourth to the sixth century, and the foundations also revealed a still older pagan sanctuary of Asclepius from Roman Serdica, as Sofia was then called. In later centuries the plot belonged to Rila Monastery, which kept a dependency here.
In the sixteenth century, in the time of Sultan Suleiman the Magnificent, a mosque was raised on the spot. Wikidata gives 1528 as the start of construction, while the English Wikipedia article speaks of about 1547, so the exact date is uncertain. Tradition credits the famous architect Mimar Sinan, although the Romanian article stresses that firm evidence is lacking. The building was a large square hall under a big lead-covered dome. Its minaret was made of dark granite, which gave the mosque the popular name Black Mosque (Kara Camii). It was also called the Imaret Mosque after a nearby kitchen for the poor, and around it stood a madrasah, a caravanserai and a hammam.
The minaret collapsed in an earthquake in the nineteenth century and was never rebuilt. After the Liberation of Bulgaria in 1878 the mosque was no longer used for prayer. It served first as a military warehouse and later as a prison, and the neighbouring madrasah was also used as a jail.
In 1901 the Russian architect Alexander Pomerantsev, known for the Upper Trade Rows on Red Square, proposed turning the derelict building into a Christian church. The Bulgarian architects Yordan Milanov and Petko Momchilov designed the new parts in a traditional Neo-Byzantine style. Only the central hall and the dome of the mosque were kept. Four oval bays, a narthex, an altar section and a bell tower were added, the minaret and the madrasah were taken down, and the work lasted from May 1901 to May 1902.
The church was consecrated on 27 July 1903 and dedicated to Saints Cyril and Methodius and their five disciples, known in the Orthodox tradition as the Sedmochislenitsi, the Seven. Tsar Ferdinand was recognised as the main donor, and the iconostasis is the work of the Filipov family of master carvers from Debar. The full interior decoration was only completed in 1996, nearly a century after the conversion began.
Curious facts about Seven Saints Church
