It was built in the 6th century, in the same wave of construction as the Hagia Sophia in Constantinople. In 1329 it gave its name to the city. It was destroyed several times and during the Ottoman rule it was used as a mosque. It was built over an even older 4th-century church, which can be explored through its excavated crypts and tombs.
The Saint Sofia Church is a Bulgarian Orthodox church, located in Sofia, the capital of Bulgaria. Built as a church in the fourth century CE, the building was converted to a mosque in the 16th century and was restored as a basilica during the 19th and 20th centuries. It is one of the oldest churches in Sofia. In 1329 CE, the town of Serdica was renamed as Sofia, after the church.
