The Château d'Aguilar is one of the so-called Cathar castles. The design of the castle witnesses the practical military thinking of the 12th century. The castle consists of an inner keep built in the 12th century, surrounded by an outer pentagonal fortification from the 13th century. This fortification is oriented such that its point guards the side most favourable to attackers. The keep and the inner hexagonal fortification is flanked at each corner with semi-circular guard towers, each equipped with archery outlooks. The strategic location of the castle on a hill overhanging the plain of Tuchan allows supervision of the Corbières. Despite this, the castle is easily accessible from the plains because of its relatively low elevation of 321 metres.
There is a small underground chapel of Saint-Anne below the keep.
The earliest building at this location belonged to the count of Fonnollède since 1021. In the 13th century, the keep that had replaced earlier buildings was bequeathed by the viscounts of Carcassonne to their vassal, the Ternes.
In 1210, it was invaded and occupied by Simon de Montfort, whose soldiers took and held the owner Raymond de Termes in a dark dungeon in the Carcassonne. Militarily, the castle lay dormant for the next 30 years, until Raymond's son Oliver de Termes took back the castle in the brief revolt against the crusaders. Aguilar became the refuge of many faydits, Cathar knights and lords without strongholds. In 1246, a royal garrison was installed to supervise the Aragon frontier.
Olivier, however, eventually made an alliance with king Louis IX, who purchased the castle from him in 1260. Despite the heavy fortifications, the castle would be continually under siege by opposers to the French or Spanish rulers until the 16th century.
When the border was pushed back to the south of Roussillon by the treaty of the Pyrenées, the castle gradually lost its strategic importance, and was eventually abandoned in 1569. Today it is in decrepit condition. Since 1949, it has been listed as a monument historique by the French Ministry of Culture.
The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
