Fort Victor-Emmanuel, Military fortress in Aussois, Savoie, France.

Fort Victor-Emmanuel stands on a rocky spur at about 1,350 metres above Aussois, in the Maurienne. Its eight buildings climb the slope in stepped sections of light tan and grey masonry: a long block with rows of small arched openings at the top, staggered rectangular buildings with square windows and low pitched roofs below, and a broad flat-roofed structure at the base.

Fort Victor-Emmanuel was built in 1818 under Victor Emmanuel I to protect the Kingdom of Sardinia, to which the Maurienne then belonged. It forms part of the Barrière de l'Esseillon, a line of forts guarding the valley. The site is now in need of restoration.

The fort's name recalls Victor Emmanuel I, King of Sardinia, who ordered its construction in 1818 when the Maurienne belonged to his kingdom. It is one of several forts forming the Barrière de l'Esseillon, a line of defences guarding the road to Italy. Today the Via Ferrata du Diable starts and ends at the fort.

The site is freely accessible throughout the year but prepare for walking the last stretch during winter when snow blocks vehicle routes. Good weather allows easier access by road, making planning ahead worthwhile.

Fort Victor-Emmanuel is the start and end point of the Via Ferrata du Diable, a secured climbing route on the rock faces around the fort; its sections are graded B to D/E. The eight buildings of the fort stand on a mountain spur at about 1,350 metres and are in need of restoration.
