The Antoniev Monastery rivalled the Yuriev Monastery as the most important monastery of medieval Novgorod the Great. It stands along the right bank of the Volkhov River north of the city centre and forms part of the Historic Monuments of Novgorod and Surroundings, a World Heritage Site.
The monastery was founded in 1117 by St. Anthony of Rome (Antony Rimlyanin), who, according to legend, flew to Novgorod from Rome on a rock (the alleged rock is now in the vestibule just to the right of the main door into the Church of the Nativity of the Mother of God beneath a fresco of Bishop Nikita of Novgorod). Antonii was consecrated hegumen of the monastery in 1131 by Archbishop Nifont (1130–1156) and was buried beneath a large slab to the right of tha altar in the same church.
The Church of the Nativity of the Mother of God, like the Church of St. George in the Yuriev Monastery, is one of the few three-domed churches in Russia. It is also one of the few buildings in Russia which survived from the 12th century. It was founded by Antonii in 1117 and completed in 1119. There are some frescoes from the Middle Ages still extant, most notably in the apse, but most are from the 16th or 17th centuries and are in some disrepair.
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.
