First property of the counts Catalans, it becomes at the end of the xth century possession of the house of Carcassonne. From the twelfth century, it belongs to the family of Termes.
Olivier de Termes, opponent of the Crusade against the Albigenses and defender of the Cathars, dispossessed of his castle of Termes by Simon de Montfort makes Aguilar his main residence and a gathering place to support the revolt of Raymond Trencavel before the siege of Carcassonne in 1240.
After several passages in the hands of the King of France to those of Olivier de Termes, the castle of Aguilar becomes definitively royal fortress in 1261. Enlarged and strengthened it becomes one of the five sons of Carcassonne and defends the Franco-Aragonese border.
With the signing of the Treaty of the Pyrenees which pushes back the border in 1659, Aguilar loses all defensive interest and is gradually abandoned.
In 1949, the castle is listed as a Historic Monument. Since then, several restoration, security and enhancement campaigns have taken place. A lice release campaign has been running since 2016 and reveals the face of Aguilar every year.
