Ouvrage Col du Granon

Ouvrage Col du Granon is a fortified military complex standing at 2,329 meters with three main structures: an entry block, an infantry block, and an observation block overlooking surrounding valleys. The structure contains machine gun positions with twin emplacements, concrete reinforcements, and specialized ventilation systems designed for extended occupation.

The complex was built between 1939 and 1940 as part of the Maginot Line extension to protect the Briançon region during Italy's invasion of France. It served as a key defensive position during the opening stages of World War II in the Alps.

The fortification reflects French military engineering of the 1930s through its network of underground galleries connecting different defensive positions and observation points across the mountainside.

The site sits at high altitude and is accessible only during warmer months when snow and ice have melted. Visitors should arrive with sturdy equipment, weather-resistant clothing, and good physical fitness since the climb is demanding and the path exposed.

The garrison consisted of around 70 soldiers from the 82nd Alpine Battalion stationed there until February 1940, when extreme weather forced most troops to evacuate. This withdrawal reveals just how severe conditions were at this high-altitude position.
