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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
