Chateau Quéribus is one of the Cathar castles that fell to the King of France/Rome Pope during the early 13th Century Albigensian Crusade. After what is now south France was rolled up into French territories, Louis IX (the “saint”) ordered the fortress and many other former cathar castles manned to guard his new border against Spain. In those days, the French-Spanish border ran not far south of the Aude Valley.
Sixty-some cathars manned the fortress during its final days during the crusade. Louis reduced that number to about 20. By the 16th Century, seven lucky souls were exiled to wind, sun, and drought in order to guard the castle.
On clear days, you can see the Mediterranean from the castle walls.
If vertiginophobia means “where the hell are the guard rails” I guess I have it.
