Situated on the Mtkvari river, Urbnisi was an important city in ancient and early medieval Iberia as Georgia was known to the Greeks and Romans. Urbnisi Church is a 6th-7th-century three-nave basilica which was rebuilt twice in the 10th and 17th centuries. Quite a simple and large church, it is based on twelve strong pillars for three naves. There are many inscriptions on the walls of the monastery which are thought to be the examples of the 6th-7th-century Georgian alphabet.
References:The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
