As part of the Grand Duchy of Moscow, Zaraysk was one of the fortresses forming a part of the Great Abatis Border, a fortified line of felled trees, barricades, fortresses, ditches, which were built by Russians as a protection against the hordes of the Crimean and Kazan Tatars. In 1531, a stone kremlin was built in place of the former wooden citadel. The Tatars failed to take the fortress during their raids in 1533, 1541, and 1570. It was briefly captured by the Lisowczycy during the Time of Troubles.
The brick-and-limestone kremlin in Zaraysk still stands and is kept in a rather good condition. The citadel is very small and has a rectangular shape, with only six towers, two of which are pierced by the gates.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.
