The Cathedral of St Demetrius (1194-97) is a royal church, built to the order of Grand Prince Vsevolod III. It is cubic in form, with three internal naves and a helmet dome. The cathedral is one-domed and four-pillared. Originally it was surrounded by galleries with towers that connected it to the prince's palace. They were demolished during the restoration in the 19th century.
The church is famous for its white-stone carvings - its walls are decorated with ca. 600 reliefs, depicting saints, mythical and real animals. Most of the reliefs are preserved in their original form, some have been replaced during the restoration of the 19th century. Out of the internal decoration a few fragments of frescoes of the 12th century have survived, particularly fragments of the Last Judgement composition. Currently, the cathedral is a part of the Vladimir-Suzdal open-air museum.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.
