Samtavisi is an eleventh-century Georgian Orthodox cathedral 45km from Tbilisi. According to a Georgian tradition, the first monastery on this place was founded by the Assyrian missionary Isidore in 572 and later rebuilt in the 10th century. Neither of these buildings has survived however. The earliest extant structures date to the eleventh century, the main edifice being built in 1030 as revealed by a now lost stone inscription. The cathedral was built by a local bishop and a skilful architect Hilarion who also authored the nearby church of Ashuriani. Heavily damaged by a series of earthquakes, the Cathedral was partially reconstructed in the 15th and 19th centuries. The masterly decorated eastern façade is the only survived original structure.
The Samtavisi Cathedral is a rectangular 4-piered cruciform domed church. It illustrates a Georgian interpretation of the cross-in-square form which set an example for many churches built in the heyday of medieval Georgia. The exterior is distinguished by the liberal use of ornamental blind arcading. The apses do not project, but their internal position is marked by deep recesses in the wall. In contrast to earlier Georgian churches, the drum of the dome is taller surmounted by a conical roof. Artistically, the most rounded portion of the church is its five-arched eastern façade, dominated by the two niches and enlivened by a bold ornate cross motif.
Beyond the main church, the Samtavisi complex includes a badly damaged two-storied bishop’s residence, a small church (5.8х3.2m), and a three-storied belltower (5.7х7.3m) attached to the 3-5m high fence made of stone and brick. All these structures date to the 17th-18th centuries.
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.
