Kluže Fortress

Highlight • Historical Site

The Kluže Fortress is a fort near the town of Bovec in northwestern Slovenia.

The original fortress was built in 1472 near Bovec on the road between Cave del Predil and Carinthia. Its 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 Venice and the Habsburgs. However, for the time being it remained as an ecclesiastical dependence of Cividale and Aquileia. At the end of the 18th century it was entirely under Austria's administration, and remained so until 1918. In 1796 and 1797 fighting took place around the fort, as Napoleon's army pushed through the Koritnica gorge. Napoleon's forces took the fort in 1797 by placing artillery at a higher elevation (where Fort Hermann now stands). The fortress was then destroyed. The current fort was built upon the site by the Austrians in the late 19th century. Fort Hermann, covering the higher elevation, was built at the same time. The two are linked by a trail and a tunnel. Fort Hermann was heavily damaged and rendered unusable by Italian artillery bombardment in 1915.

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.

Arnoldstein Monastery Ruins

Highlight • Historical Site

When the monastery was dissolved in 1783 under Joseph II, the influence of the Benedictines ended and the old walls were left to themselves. Exactly one hundred years later, a fire devastated the place and with it the monastery. Revitalization work has been taking place since 1991.

Today, the former ruins are Arnoldstein's cultural center, where civil weddings, celebrations, conferences and various cultural events such as concerts, readings and exhibitions also take place.

Fort Hensel

Highlight • Historical Site

Fort Hensel used to be one of the most important structures of the Austro-Hungarian defense system; it was built on the Tschalawài cape in 1809, near the village of Malborghetto. It was designed by engineer Captain Friedrich Hensel during the Napoleonic era, as French troops were moving back through the Friulian valleys to the northern border. The two armies clashed on May 15 of the same year and the fort was occupied by French troops for two years.
At the end of the Napoleonic period, the fortress was restored in the middle of the warring century and again in 1884, when the Kingdom of Italy had to keep an eye on the border. The building was restored, modernized and converted into a major fortress capable of 18 guns and a 360-degree defense package. It was named Hensel for its attachment, died defending it in May 1809. It remained inactive for 30 years, then was reactivated during the Great War, garrisoning 21 officers and 567 soldiers.
The fortress was formed by two buildings 50 meters apart: the first, higher up, would house a barracks, two howitzer batteries and a two-storey bastion with four guns, while the second building consisted of two towers connected by a battery with a total of eight guns. Being equipped with good guns and also accommodating lower caliber guns, Fort Hensel became one of the main targets of the Italian artillery from the tops of the Dogna Valley, along the former frontier. More than two thousand high-caliber shells were fired in the summer of 1915 alone, while about 4,500 shells were counted during the war, destroying the fortress in a heap of rubble.


Today, among the dense growth of the cape, we can still see the ruins of such buildings. The visit starts from the small parking lot on the SS13 road, past the village of Malborghetto. The monument of the "Hensel Lion" is clearly visible on the rock face of the cape.
If you climb all the way up you can see the gun emplacements, from where you can carefully descend and visit some of the tunnels and chambers.

Predel Fortress Ruins

Highlight • Historical Site

The Fortress Predel was one of the six forts that formed the system of Carinthian forts. It stands a few hundred meters from the Passage Pass. The first fort was erected during the Napoleonic Wars. During the war, it was burned twice as a result of angry fighting. In 1848 they decided to build a new one on the site of the old fortress. It served its purpose until 1880, when a commission found that the fort no longer complied with modern military regulations, so it was turned into a military warehouse. The building had this function until the end of the First World War. Because no one maintained the building after the war, it collapsed, so that only relatively well preserved walls can be seen today.

May 28, 2026, Predel Fortress Ruins

The remains of the fortress below the pass and the Predel/Predil pass date back to the second half of the 19th century. It was in the same place that, as early as 1808, the Austrians began to build a log fortification on stone foundations. The work was interrupted due to the harsh winter, which, in May 1809, when the French army penetrated and was advancing in the Soča (Isonzo) river valley and the Kanalska dolina/Kanaltal valley, did not play in their favor.

The story of the Kluža fortress is caught in the extraordinary nature, between the steep slopes of Rombon, Slemena and the emerald green, 70 m deep Koritnica riverbed. Here you will feel and admire the drafts of the past that marked this important strategic position, also called Bovška vrata. The Kluže fortress is located 4 km from Bovec in the direction of the Predel pass.
