1. The Church of St. George, also known as St. George Rotunda, is one of the oldest buildings in Sofia, Bulgaria. It is believed to have been built in the 4th century during the reign of Emperor Constantine the Great. The church is located in the heart of the city, near the President’s Office, the Council of Ministers, and the National Assembly.

The architectural style of the Church of St. George is predominantly Byzantine, with influences from early Christianity and Roman architecture. It is a cylindrical structure with a diameter of 9.5 meters and a dome at the top. The interior of the church is decorated with exquisite frescoes dating back to the 10th and 14th centuries, depicting scenes from the life of Jesus Christ and the saints.

One interesting fact about the church is that it has served various purposes throughout history. It was initially built as a mausoleum for the Roman Emperor Constantine the Great’s daughter, Constantina. Later, during the Ottoman period, it was converted into a mosque. It was restored as a Christian church in 1878 after Bulgaria gained independence from the Ottoman Empire.
