Cathars and Catharism in the Languedoc:   Cathar Castles:   Coustaussa

The original castle was built in the Trencavels - Viscounts of the Razès - in the twelfth century.  Sited above the Sals River (so called because of its salty water) it controlled the Sals Valley in the modern Aude département and thus the only significant route between the Aude Valley and the Corbières.  Just across the Sals valley is Rennes-le-Château. 

On their way back from Termes in late November 1210, Simon de Montfort and his Crusaders found the Château at Coustaussa already abandoned, and so carried on to Puivert.  Apparently the garrison at Coustaussa, like the one at Le Bézu had lost heart after the fall of Termes. 

Like many other strongholds Coustaussa returned to its traditional allegiance the following year. According to the Historia Albigensis [280], Simon de Montfort was at Narbonne with a crowd of newly arrived Crusaders when he heard the news. He immediately hurried off to Coustaussa and attacked it. The castle was surrendered after "a few days", after which Simon set off for Castelnaudry.

After the Crusades, the Castle came into the possession of the de Montesquieu family. 

The present Château was apparently still in good shape until the nineteenth century, when an enterprising local realised that he could turn a few Francs by stripping out and selling the woodwork.
