Yarmouth Castle is an artillery fort built by Henry VIII in 1547 to protect Yarmouth Harbour on the Isle of Wight from the threat of French attack. Just under 30 m across, the square castle was initially equipped with 15 artillery guns and a garrison of 20 men. It featured an Italianate 'arrow-head' bastion on its landward side; this was very different in style from the earlier circular bastions used in the Device Forts built by Henry and was the first of its kind to be constructed in England.
During the 16th and 17th centuries the castle continued to be maintained and modified; the seaward half of the castle was turned into a solid gun platform and additional accommodation was built for the fort's gunners. A bulwark was built on the east side of the castle and an additional gun battery was placed on the town's quay, just to the west. For most of the English Civil War of the 1640s it was held by Parliament; following the Restoration, it was refortified by Charles II in the 1670s.
The fortification remained in use through the 18th and 19th centuries, albeit with a smaller garrison and fewer guns, until in 1885 these were finally withdrawn. After a short period as a coast guard signalling post, the castle was brought back into military use during the First and Second World Wars. In the 21st century, the heritage organisation English Heritage operates the castle as a tourist attraction.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.
