The Orkesta Runestones are a set of 11th-century runestones engraved in Old Norse with the Younger Futhark alphabet that are located at the church of Orkesta.
Several of the stones were raised by, or in memory of, the Swedish Viking Ulf of Borresta, who during the 11th century returned home three times with danegeld. The leaders of the three expeditions were Skagul Toste (Tosti), Thorkell the Tall (Þorketill), and Canute the Great (Knútr). This Ulfr also made the Risbyle Runestones in the same region, and he was mentioned on the lost runestone U 343.
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.
