The Church of Saint George is a Late Antique red brick rotunda in Sofia, Bulgaria. Built in the early 4th century as Roman baths, it became a church inside the walls of Serdica, capital of ancient Dacia Mediterranea during the Roman Empire and Byzantine Empire. The Early Christian church is considered the oldest building in modern Sofia and belongs to the Bulgarian Orthodox Church.
The building, a cylindrical domed structure built on a square base, is famous for the 12th-, 13th-, and 14th-century frescoes inside the central dome. Three layers of frescoes have been discovered, the earliest dating back to the 10th century. Frescoes of 22 prophets over 2 metres tall crown the dome. Painted over during the Ottoman period, when the building was used as a mosque, these frescoes were only uncovered and restored in the 20th century.
Outstanding among all the murals is the one from the 10th century, created most probably during the reign of the emperors Simeon I the Great, Peter I and Samuil. The soulful human face of an angel, painted under the dome, is unique and one of the most influential examples of the high mastery of Bulgarian artistic school of the golden age of the First Bulgarian Empire.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
