The simple red brick church dates back to the 6th/7th century when it was the site of Serdica's necropolis. Beneath it lie several earlier churches dating back to the early 4th century. You can now visit some of the remains of the ancient buildings and tombs that lie under the church as part of a brand new fascinating museum opened to the public in May 2013.
During the Ottoman yoke it was turned into a mosque, but after an earthquake in 1818 toppled the minaret and another some 40 years later killed the Imam's two sons, it was abandoned and restored as a church after the Liberation.
This is a very popular church for weddings and christenings.
