Château d'Aguilar
The Château d'Aguilar is a 12th‑/13th‑century hilltop fortress in Tuchan, Aude, France, often listed among the Cathar castles. It comprises a central keep and concentric fortifications sited to dominate the surrounding plain and Corbières Massif. The ruin visible today preserves lengths of its inner and outer curtain walls and several rounded towers.

As it stood in 1250
The shape it held in its prime.
In its prime the castle read as a compact, multi‑layered hilltop fortress: a central stone keep set within an inner hexagonal curtain, itself enclosed by a larger pentagonal outer curtain whose point faces the most vulnerable approach. Each corner of the inner fortification is flanked by semi‑circular guard towers with narrow arrow slits; the outer wall carries rounded corner towers and crenellated battlements. Built of pale local limestone, the complex sits on a rocky, scrubby hill above a broad plain, with intact roofs and battlements at the time.
Its story
The story of Château d'Aguilar.
The Château d'Aguilar is one of the so-called Cathar castles, set on a hill overhanging the plain of Tuchan in the Aude. The earliest building on the site belonged to the count of Fenouillèdes from 1021; in the 13th century the keep that had replaced it was bequeathed by the viscounts of Carcassonne to their vassals, the Counts of Termes.
In 1210 the castle was invaded and occupied by Simon de Montfort, whose soldiers took its owner Raymond de Termes and held him in a dark dungeon at Carcassonne. In October 1260 Olivier de Termes sold Aguilar to Louis IX, along with the villages of Termes, Davejean and Vignevieille.
The design shows the practical military thinking of 12th-century architecture: an inner keep flanked at each corner by semi-circular guard towers with archery outlooks, wrapped in a 13th-century pentagonal outer fortification whose point guards the side most favourable to attackers. A small underground chapel of Saint-Anne lies below the keep, and the ruin still controls the Corbières Massif.
