Château de Termes

The castle sits on a promontory in the limestone Corbières, some forty kilometres south-east of Carcassonne, with deep ravines closing three of its sides and access only from the south, where the rock was cut back to form a defensive ditch. It was the seat of a powerful feudal lordship, and the site gave its name to the surrounding country, the Termenès. Its lords are known from the second half of the eleventh century, mentions of the castle multiply through the twelfth, and a few remains at the summit belong to that first castle of the lords of Termes. A chapel appears in a deed of partition of 1163. Until the thirteenth century the castle's history ran with that of the county and later viscounty of Carcassonne, and with the Trencavel viscounts.

A fortified village of the twelfth century stood on the southern flank of the hill, its walls and staggered entrance still traceable, and a smaller work called the Termenet stood on a rock to the north above the gorges, of which only very slight remains survive. Under Raymond de Termes, a vassal of the viscount of Carcassonne in 1209, the castle became the refuge of a good many Cathars.

Simon de Montfort resolved to take Termes in 1210, and the siege that followed ran four months, from August to November, the hardest of the first period of the Albigensian Crusade. An exceptionally dry summer and autumn emptied the castle's water tanks, and Raymond offered to surrender. When the crusaders came forward to take possession they were met with a hail of arrows: a heavy storm overnight had filled the cisterns again, and the defenders held out a while longer.

The Chanson de la croisade albigeoise carries the episode further. The garrison had wine enough but had run out of water; when the sudden downpour came they drank from it, filled their jugs, kneaded fresh bread and made new soups, and a frightful colic took hold of them. Weakened by dysentery and exposed to the fire of numbers of siege engines, the garrison tried to slip out by night. The alarm was raised, the fugitives were caught and killed, and Raymond surrendered the castle to Montfort.

After Montfort's death Raymond recovered the castle, but was soon forced to give it up again, this time to the king of France; by 1228 Termes had passed under direct royal control. Rebuilt in the thirteenth century as a royal garrison, and drawn after the Treaty of Corbeil into the network of royal fortresses holding the frontier with Aragon, it became one of the five sons of Carcassonne alongside Aguilar, Quéribus, Peyrepertuse and Puilaurens, the ensemble thrown forward from the Cité of Carcassonne and built in the thirteenth century by the Capetians under Louis IX.

Royal architects rebuilt most of the site at the end of the thirteenth and the beginning of the fourteenth century, once Termes had become a fortress facing Aragon: two concentric enceintes, the lower and better preserved of them about 125 by 70 metres, with flanking works and buildings inside both circuits. Documents record its occupation through the late Middle Ages and the early modern period, and at one point it was held by eight sergeants-at-arms where fifteen had served before. The castral village was probably moved down into the valley to its present position after the king of France took possession in the thirteenth century, a pattern recognised at a number of other castle sites in Languedoc in the same period.

The castle lost its purpose in the seventeenth century, and a band of brigands took it over and used it as a base from which to terrorise and pillage the country round about. To put an end to that it was demolished by royal decree: a master mason from Limoux spent 1653 and 1654 blowing up the walls with gunpowder and reducing them to heaps of rubble, and the bill for the work survives, at 14,922 livres and 10 sous. Of the keep only a few collapsed sections of wall are left, probably brought down by those charges. The dismantling came shortly before the Treaty of the Pyrenees carried the frontier with Spain southward.

The castle and its surroundings have been classified as a natural site since 1942. The ruin was inscribed as a monument historique on 25 June 1951 and classified on 25 September 1989, and since 1989 it has belonged to the commune of Termes. An order of 27 December 2023 inscribed the whole of the remains, every element of the enceinte and of the castral village, and an order of 4 December 2024 classified them.

The commune has worked for some twenty years on the site, one of the anchor sites of the Pays Cathare programme run by the Conseil général de l'Aude. The ruin has had substantial consolidation work, archaeological soundings and architectural survey, and it is open to visitors, a fifteen to twenty minute walk up from the village. Excavations directed by the archaeologist Jean-Paul Cazes have uncovered the thirteenth-century staircase that led up to the castral church, and the great hall of the royal period was cleared in 2007. On 26 July 2026 the Royal Capetian Fortresses of Languedoc were inscribed on the UNESCO World Heritage list at the 48th session of the World Heritage Committee, Termes among them, with the ramparts and castle of Carcassonne, its four fellow sons of Carcassonne, and the castles of Montségur and Lastours.
