Bothwell Castle is a large medieval castle, sited on a high, steep bank, above a bend in the River Clyde. Construction of the castle was begun in the 13th century by the ancestors of Clan Murray, to guard a strategic crossing point of the Clyde. Bothwell played a key role in Scotland's Wars of Independence, changing hands several times.
The huge cylindrical donjon was built in the 13th century, but before the rest of the castle was completed it was severely damaged in a series of sieges. Rebuilding in the early 15th century enlarged the castle, but it was abandoned by the 18th century. The present ruin is rectangular, with the remains of the donjon to the west, and the later Great Hall to the east. The courtyard is enclosed by long curtain walls, with round towers at the south-east and south-west corners.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.
