Fort de l'Olive

Fort de l'Olive is a military fortification built high in the French Alps with substantial stone walls occupying a large footprint on the mountainside. The installation dominates the surrounding landscape and its position commands several key passes through the mountains.

The fort was built in the 1880s as part of a comprehensive French defensive system to protect the eastern mountain passes. It was a response to the changed military situation in the Alps following the Franco-Prussian War.

The fort represents French military engineering from the late 19th century, designed to protect the border against potential Italian invasions.

Visitors reach the fort via a mountain hiking trail that requires several hours of walking and good physical fitness. The terrain is steep and exposed, so weatherproof gear and proper footwear are necessary.

The fort was never directly captured despite coming under artillery fire during World War Two. It stands today as a silent witness to the mountain border conflicts that shaped the region during the 20th century.
