You might not think of a botanic garden as a historic site, but the Royal Botanic Gardens at Kew, London (a UNESCO World Heritage Site) have a firm place in the history of gardening. Established from a collection of royal estates in 1759, they demonstrate different garden styles through the centuries. The gardens are also home to 44 historic buildings, including royal residences, Victorian greenhouses and garden follies.
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.
