Fort Gorazda was built by the Austro-Hungarian Empire near Kotor. The fortress's predecessor was built prior to the 1869 uprising. The current fort was built between 1884–86 and replaced an earlier structure; its most notable feature is a 100-ton Gruson rotating turret on its roof, the last remaining example of its type. The fort was used by the Austrians in artillery duels against Montenegrin batteries stationed on Mount Lovćen during the First World War. The Montenegrins were unable to destroy it and were pushed out of range in 1916 by an Austrian offensive. The damage to the fort was repaired and its guns were removed to support the Austrian field army. It was used as a depot by the Yugoslav Army until as recently as the early 1990s. It was subsequently abandoned and can be visited by the public.
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.
