History of the area

The Fort du Replaton Modane has a long history tied to both world wars and France’s mountain defences.

1. Construction (1885–1891)

The fort was originally built with stone masonry and later reinforced with concrete between 1892 and 1894. It was specifically designed to withstand bombings while also serving as a strong defence against Italian advances.

2. Military Role Pre-WWI

By 1913, the fort was fully armed and had become a vital defensive stronghold for the French army. Because of its strategic position, it protected not only the valley but also the Fréjus tunnel, one of Europe’s most important railway links.

3. Maginot Extension (1930s)

It was later incorporated into the Alpine Line, an extension of the Maginot defences. During this period, it was modernised with reinforced gun positions and new observation points.

4. World War II (June 1940)

The fort played a crucial role in resisting the Italian army during the Battle of the Alps. During this fight, the French troops relied on it to hold the line and successfully prevent Italian advances through the tunnel.

Today, while the fort is closed inside, the exterior walls are a must-see for any history lover visiting the area.
