This majestic fort above the Koritnica gorge is one of the most visited cultural sights in the Soča valley. It is an important monument to the defence against Turkish invasions, Napoleon's army and attacks during World War I.
The Koroška fort on the slope of Mt. Rombon was built as a support to the Kluže Fort, between years 1897 and 1900, i.e. in Austria-Hungary. Med prvo svetovno vojno je bila zaradi silovitega italijanskega obstreljevanja močno poškodovana. Today, informative signs have been placed next to the debris of the fort. Access to Fort Hermann: By foot, from the Kluže Fort, on a wide marked route, which is carved into a rocky slope, through a 100 m long illuminated stone tunnel and then on the left path that climbs the Rombon. The walk to the fort takes a little less than half an hour.
