The Pskov Krom (or Pskov Kremlin) is an ancient citadel in Pskov. In the central part of the city, the Krom is located at the junction of the Velikaya River and smaller Pskova river. The citadel is of medieval origin, with the surrounding walls constructed starting in the late 1400s. The Krom was the administrative and spiritual centre of the Pskov Republic in the 15th century. In 2010, two of the towers of seven (the Vlasyevskaya, which dates to the 15th or 16th century, and the Rybnitskaya, which dates to 13th or 14th) were damaged in a fire.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.
