Château d'Agel was first mentioned in 1100. In the early 12th century the area was rocked by the scandal of the Cathar Wars or Albigensian Crusade. A local form of Christianity was becoming ever more popular and according to some had already become the majority religion of the area. The Catholic Church regarded it as both a heresy and a threat. The 'heresy' was strongest in the county of Toulouse and all over Languedoc, where vassals of the Count of Toulouse refortified a line of castles to protect themselves against Papal forces. Agel was one of that line of castles refortified to resist the Pope's forces.
The Crusade against the Cathars, led by Simon de Montfort, raged throughout the Languedoc. In Simon's bid to take nearby Minerve in 1210, the château d'Agel was almost entirely destroyed by fire. In July of that year, Minerve fell, and the 180 Cathars who had taken refuge there met their end on a burning pyre.
The Treaty of Paris, which annexed Languedoc to France in 1220, put an end to the Crusade. Guiraud de Pépieux, who had escaped the massacre, set about restoring the château for his descendants. Notarial records dating back to the year 1300 mention another Guillaume de Pépieux as Lord of Aigues-Vives and Agel.
The architecture of the Château d'Agel reflects its continued use over the centuries. Thus for example window styles, vary from the tiny windows of the stark 12th century fortress to the beautiful windows of the Renaissance with ornamental balusters and capitals. During the 17th century, Renaissance embrasures were replaced on the principal frontage by broad bays with small squares in the style of Trianon.
By the first half of the 20th century, the Château had fallen into disrepair, and the northern wing in particular had become a ruin. In the 1960s the Ecal family began the task of restoring the property and its gardens to their former glory. Today Château d'Agel is a grand hotel.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
