Peyrepertuse is a ruined fortress and one of the Cathar castles of the Languedoc located in the French Pyrénées in the commune of Duilhac-sous-Peyrepertuse, in the Aude département.
This is the right way to photo these Cathar castles. They were built on hilltops to look down on the valleys, the routes where merchants traveled and armies advanced. Your photo shows the position beautifully.
