Rotunda of Galerius
Ροτόντα
A UNESCO World Heritage Site, this circular monument was built by Roman emperor Galerius in the 4th century AD and later converted into a church and a mosque. Gold-ground mosaics survive inside its dome.
The Rotunda of Galerius was built around 306 AD and may originally have served as Galerius’s mausoleum or a temple. Its walls are 6 metres thick. It was later converted into the Church of St George, and during the Ottoman period it became a mosque. A minaret still stands beside it, a rare survival in Greece. Inside the dome, exquisite 4th-century gold-ground mosaics remain, and the building forms part of the UNESCO World Heritage Site “Early Christian and Byzantine Monuments of Thessaloniki.” Admission is about €6. Opening hours vary by season, and it is often closed on Tuesdays.
