Kluže fortress, Julian Alps, Slovenia
Kluže is a fort near Bovec in the Primorska region in Northwestern Slovenia.
The fortress was built in 1472 near Bovec on the road between Cave del Predil and Carinthia. It likely original purpose was defence of Friuli against the Turks. In the course of the 16th century Bovec came under Austrian authority as a result of the wars between Venica and the Hapsburgs. However, for the time being it remained as an ecclesiastical dependence of Ciudad and Aquileia. At the end of the 18th century it was entirely under Austria's administration, and remained so until 1918. In 1796-1797 fighting took place around the fort, as Napoleon's army pushed through the Koritnica gorge.
In 1903 part of Bovec was destroyed by a fire. What remained standing, was ravaged in World War I, when the Italian-Austrian front (Battles of the Isonzo) crossed through the valley as the battle cut from north to south.
