Château de Quéribus is a ruined castle in the commune of Cucugnan. It is one of the 'Five Sons of Carcassonne', along with Aguilar, Peyrepertuse, Termes and Puilaurens: five castles strategically placed to defend the French border against the Spanish, until the border was moved in 1659.
Quéribus was first time mentioned in 1021 when it was one of the main Barcelonan strongholds north of the Pyrenees.
It is sometimes regarded as the last Cathar stronghold. After the fall of Montségur in 1244 surviving Cathars gathered together in another mountain-top stronghold on the border of Aragon. In 1255, a French army was dispatched to deal with these remaining Cathars, but they slipped away without a fight, probably to Aragon or Piedmont - both regions where Cathar beliefs were still common, and where the Occitan language was spoken.
Quéribus is high and isolated. It stands on top of the highest peak for miles around. In 1951 restoration work on the turret began, and between 1998-2002 a complete restoration of the castle was undertaken: the castle is now accessible to visitors.
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.
