Auchagallon Stone Circle is the remains of a Neolithic or Bronze Age burial cairn, surrounded by a circle of fifteen stones. The cairn and stone circle is situated on a slight ledge of a west-facing slope, overlooking Machrie Bay. The circle comprises fifteen blocks varying in height from 0.5 metres to 2.3 metres. The stones are of red sandstone, except two which are a pale grey granite. The circle has a maximum diameter of 14.5 metres.
In the centre is a large stone cairn. Antiquarians digging here in the 19th century found a burial cist in the centre, although there are no records of any other remains. Although the monument is now called a stone circle, it was probably built as a kerbed cairn.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.
