Jvari is a sixth century Georgian Orthodox monastery near Mtskheta. Along with other historic structures of Mtskheta, it is listed as a World Heritage site by UNESCO. It stands on the rocky mountaintop at the confluence of the Mtkvari and Aragvi rivers, overlooking the town of Mtskheta.
According to traditional accounts, on this location in the early 4th century Saint Nino, a female evangelist credited with converting King Mirian III of Iberia to Christianity, erected a large wooden cross on the site of a pagan temple. A small church was erected over the remnants of the wooden cross in circa 545 AD. The present building is generally believed to have been built between 590 and 605 by Erismtavari Stepanoz I.
The importance of Jvari complex increased over time and attracted many pilgrims. In the late Middle Ages, the complex was fortified by a stone wall and gate, remnants of which still survive. During the Soviet period, the church was preserved as a national monument, but access was rendered difficult by tight security at a nearby military base. After the independence of Georgia, the building was restored to active religious use.
The Jvari church is an early example of a four-apsed church with four niches. Between the four apses are three-quarter cylindrical niches which are open to the central space, and the transition from the square central bay to the base of the dome's drum is effected through three rows of squinches.The Jvari church had a great impact on the further development of Georgian architecture and served as a model for many other churches.
Varied bas-relief sculptures with Hellenistic and Sasanian influences decorate its external façades, some of which are accompanied by explanatory inscriptions in Georgian Asomtavruli script. The entrance tympanumon the southern façade is adorned with a relief of the Glorification of the Cross, the same façade also shows an Ascension of Christ.
Erosion is playing its part to deteriorate the monastery, with its stone blocks being degraded by wind and acidic rain.
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.
