The Church of Saint George is a late antique red brick rotunda in Sofia, Bulgaria. Built in the early 4th century CE as Roman baths, it became a church inside the walls of Serdica, capital of ancient Dacia Mediterranea during the Roman and Byzantine eras. The early Christian church is considered the oldest building in modern Sofia and belongs to the Bulgarian Orthodox Church.
