The Kvatakhevi monastic complex is situated near the village Kavtiskhevi at the end of the gorge cut by a stream in the northern slopes of the Trialeti Range, protected on three sides by the steep mountain slopes. It dates to the 12th-13th century, and resembles the monasteries of Betania, Pitareti, and Timotesubani in its architectural form and decoration, reflecting a contemporary canon of a Georgian domed church architecture. The overall plan is nearly a square, with the dome resting upon 2 freely standing pillars and 2 pillars fused with the ledges of the altar. The internal space of the church is formed by the arms of the cross and the dome which surmounts the crossing point.
The building has two portals, one to the south and one to the west. The façades are covered with finely hewn white stone squares. The decoration abounds in fretwork, especially around the windows and the base of the dome; the eastern façade is adorned with a large ornate cross.
Historically, Kvatakhevi was also a literary center where several manuscripts were copied. It also possessed a treasure with many artifacts of medieval Georgian jewelry, a sizeable portion of which was later acquired by and are now on display at the Moscow State Historical Museum.
The monastery was significantly damaged during Timur's invasions of Georgia in the 14th century, but was subsequently repaired, more completely under the patronage of Prince Ivane Tarkhan-Mouravi in 1854. A belfry was added in 1872.
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.
