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 control and protection of the Corbières Massif.

the castle was returned in 1250 to Olivier de Termes, the son of Raymond who had made peace with king Louis IX, for his good services during his crusade in the Holy Land.
