The Church of St George Rotunda stands in the inner courtyard of the Sheraton Sofia Hotel Balkan, between the Presidency and the Council of Ministers in central Sofia, Bulgaria. It is generally regarded as the oldest preserved building in the city. The red-brick, domed structure dates from the 4th century CE, during the reign of Constantine the Great, when Serdica was a flourishing imperial city, and was probably built as a Roman bath, civic hall or ceremonial building before being converted into a Christian church.
The rotunda is a cylindrical brick building topped with a dome roughly 14 metres across. Four semicircular niches form a cross-shaped plan inside. Over the centuries it served as a church, was damaged during the Hun invasion of the 5th century and repaired, and in the Ottoman period of the 16th century was turned into a mosque, during which the Christian paintings were covered with plaster. Excavations around the building in the 20th century revealed Roman streets, walls and the foundations of the surrounding complex, and these remains are visible in the courtyard.
Inside, the dome and walls preserve several layers of painting. The oldest fragments date from the 10th to 11th centuries. The most striking layer is the 14th-century cycle in the dome, showing prophets and angels in a Palaeologan style, along with figures of saints in the lower areas. Restoration in the 20th century uncovered the layers, which are now carefully preserved and displayed with limited lighting. A museum-style approach is used inside: the rotunda is not a gallery with labelled rooms, but visitors can study the frescoes from the floor.
The church remains an active place of worship, so services take priority over sightseeing and the interior may be closed during liturgies. The courtyard holds Roman masonry, sarcophagi and a few Christian grave markers, giving a compact overview of Sofia's layered past. The surrounding buildings were reconstructed after the Second World War bombing of Sofia in 1944, and conservation has continued since, though the delicate frescoes remain vulnerable to humidity. The Rotunda pairs naturally with the nearby Serdica Archaeological Complex and the Sveta Nedelya Church.

Why it matters
Built in the 4th century, the Rotunda is generally regarded as the oldest preserved building in Sofia. It survived Hun invasions, Ottoman conversion into a mosque and 20th-century bombing, and its layered frescoes document Bulgarian medieval painting.

Accessibility
The courtyard is accessible from the street, but the church entrance has a threshold and the courtyard surface is uneven, so mobility access is limited.
Frequently asked questions
Is the Rotunda really the oldest building in Sofia?
It is generally described as the oldest preserved building in the city, dated to the 4th century CE. Other Roman ruins in Sofia exist, but they are archaeological remains rather than standing buildings.
How long does a visit take?
Around 20 to 30 minutes covers the interior frescoes and the courtyard ruins.
Can the church be visited with children?
Yes. It is small, free and quiet, but children should be asked to stay quiet inside because it is an active church.
