Puilaurens Castle

The hill is called Mont Ardu, and the name is first written down in 958, in a charter by which Lothair confirmed the gift made by Sunifred II, lord of the Fenouillèdes, to the abbey of Saint-Michel-de-Cuxa: the provostship of Puilaurens, that is the valley of the Boulzane, also called the Sainte-Croix valley. The same document records a church of Saint-Laurent already serving as a fortified hilltop refuge in the Carolingian period.

The first castellan known by name is Pierre Catala, who appears as a witness to the acts of Guillaume de Peyrepertuse in 1217. Guillaume de Peyrepertuse himself commanded Puilaurens in 1229, and in 1242 it was held by Roger Catala, Pierre's son. A village was built all around the castle, which made Puilaurens a castrum.

During the Albigensian Crusade the castle is known for one thing only: it sheltered people. In 1240 Saurine Rigaud, a Cathar believer from Fanjeaux, found refuge at Puilaurens, where she met twelve religious, eight of them women. In 1242 Pierre Paraire, the Cathar deacon of the Fenouillèdes, stayed there, and from 1245 to 1246 several Perfect, men and women, were lodged in the castle.

Around 1250 Puilaurens passed into the royal domain. By a letter of August 1255 Louis IX ordered the seneschal of Carcassonne to fortify it, to defend the Languedoc against Aragonese incursions, and it is that campaign which set the appearance the castle has today. The Treaty of Corbeil of 1258 made it one of the fortresses on the frontier of the kingdom facing Aragon, and one of the Five Sons of Carcassonne with Quéribus, Peyrepertuse, Termes and Aguilar, each of them on its own rocky peak.

In 1260, after that first campaign of works, it held the largest garrison on the whole border: the castellan Odon de Monteuil, a chaplain and twenty-five sergeants-at-arms. A delivery recorded in 1263 lists ten salted pigs, two bushels of wheat and six setiers of good flour, along with two-foot crossbows, four of horn and two of wood, 4,100 crossbow bolts, eighteen shields and five helmets. Consolidation and fortification continued under Philip the Bold from 1270 to 1285.

The castle resisted several Aragonese attacks and remained the southernmost fortress of France, holding through two sieges. A round tower on its western side is known as the Tower of the White Lady, a lady said to be Blanche de Bourbon, great-niece of Philip the Fair, who is supposed to have stayed at Puilaurens before leaving for Spain to marry Peter the Cruel. The garrison was still being paid centuries after Louis IX: on 3 February 1534, old style, Jehan Baile, captain of Puylaurens, gave the treasurer of Carcassonne a receipt for 48 livres tournois, part of his annual wages. In 1636 the place fell by default, half the garrison being away at Port Leucate when 800 Aragonese came up from Prades and seized it.

Like the other sons of Carcassonne, Puilaurens was gradually abandoned from the Treaty of the Pyrenees, ratified in 1659, which fixed the French-Spanish border along the Pyrenean crests. A weak garrison occupied the citadel for a time; poorly defended and poorly maintained from the end of the 17th century, it was abandoned for good during the Revolution.

The ruins were classed as a monument historique by an order of 12 August 1902. A first restoration campaign in the 1950s closed two breaches above the entrance gate of the first enceinte, and a second, between 1993 and 1996, improved the reception of visitors. A full heritage survey in 2019, with photographic records and 2D and 3D surveys, graded the urgency of the work needed; the first tranche began in April 2021, making the north postern safe, rebuilding the east wall of the cistern, clearing vegetation, and restoring the south tower entire.

An order of 27 December 2023 inscribed the whole of the surviving fabric — the access chicanes, the barbican, the firing posts and every element of the enceinte — and a fresh classification order of 6 November 2024 replaced it. On 26 July 2026, at the 48th session of the World Heritage Committee, Puilaurens was inscribed by UNESCO within the serial property Royal Capetian Fortresses of Languedoc, alongside the ramparts and château of Carcassonne, the other Five Sons, and the castles of Montségur and Lastours. The castle belongs to the commune, and opens to visitors from late March to mid-November, guided tours included.
