Fort Predel, Military fort in Bovec, Slovenia

Fort Predel is a fortification in the Koroska defense line of northwestern Slovenia, located several hundred meters from Predel Pass. The structure displays remaining wall sections but has not been maintained or restored since World War I ended.

The fort saw intense fighting in 1809 during the Napoleonic Wars when French forces bombarded it, causing heavy losses among defenders. In 1880 it shifted from active military use to serve as a storage facility.

The fort's name comes from the Predel Pass beside it, and locals also call it Paßsperre Predil or Depot Oberbreth. After 1880 it served as a military depot, and today only the walls remain, with no maintained memorial inside. The site is a monument of local significance in the Municipality of Bovec.

Access to the fort is straightforward from the nearby Predel Pass, though the mountain setting requires reasonable physical fitness. Visitors should wear weather-appropriate clothing since conditions at this elevation change quickly.

The 1809 assault left only three officers, four soldiers and one gunner alive; most defenders were killed with bayonets and sabres, and some were left to burn in the fired blockhouse. The commander, Johann Hermann von Hermannsdorf, was mortally wounded in the final fight.
