The fortification was erected between 1885 and 1894, with the aim of monitoring the outlet of the Frejus railway tunnel in anticipation of a possible French attack. During the First World War, its artillery was requisitioned and moved to the Austro-Hungarian front, while on the eve of the Second World War, it was incorporated into the fortified system of the Alpine Wall. It was then requisitioned by the Germans and completely dismantled after the end of hostilities. It remained abandoned for a long time, until, starting in 1995, a recovery project was initiated, still partly ongoing, equipping the structure with a museum and a guided tour. The road that reaches it from the valley floor is yet another demonstration of the construction skills of military engineering: the dirt road gains altitude with gentle hairpin bends, bordered by dry stone walls that are still perfectly in place. Near Grange Bersac, it passes a charming little church, shortly after the route leaves the woods and ends in wide meadows near another beautiful little church, dedicated to St. Anne. From here, the dirt road splits: straight ahead leads to Pian del Sole and the Bardonecchia MTB circuit, while climbing towards Colomion, turning right, a final short climb reaches the fort. The view of Guglia Rossa and the Re Magi (Three Wise Men) group, which dominate the Bardonecchia basin, is magnificent.

A very beautiful stretch to cycle which leads from the basins to the road to the Scarfiotti refuge and then to the Sommeiller pass.

The view at the top is truly stunning; I recommend taking a walk and enjoying the scenery. I recommend going when the road is closed to cars and motorcycles, which raise a lot of dust.

Right on the edge of the SP24, a beautiful masonry structure houses two reinforced concrete basins/washhouses, with large delivery pipes. The entire complex is practically abandoned, but very fascinating. Inside, you can still clearly see the delivery pipe system and a control panel—it's likely a tank for collecting drinking water, which was used both directly in the basins and sent to homes. From the materials and style, the structure appears to date back to the interwar period. It's in a truly infamous location, in the basin between the two opposing slopes between Salbertrand and the turnoff for Fenils, after a bend, so you have to be very careful. As you climb up, narrowing down, you can even stop to get a good look and take a few photos; as you descend, it's best to avoid it—unless, due to some extraordinary astral conjunction, the road is clear of traffic.

Along the stretch of Via Roma that descends from the town onto the SP24 (going down), on one side we find a beautiful covered fountain with drinkable water; on the opposite side, an ancient house (currently [August 2025] undergoing restoration) with a wonderful carved stone portal and a beautiful wooden door.

Few remains of this historic fort on the Bardonecchia defensive line, at over 2,700 meters above sea level. It is served by dirt roads, so you're likely to encounter motorized vehicles such as motorcycles or off-road vehicles ascending or descending.

Built in the late 1800s as a military shelter for Alpine troops, the barracks served to control the passes between Italy and France. Unarmed, it served as a base for high-altitude patrols. Abandoned after the Second World War, today only the ruins remain.
