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 fortress worth seeing, unfortunately very busy.

Although the flag parade seen in some of the photos (which various users have uploaded to the highlight) could theoretically fit into a memorial for the victims of the two world wars – who came from many different nationalities – they do not belong in any context with the “Monumento ai caduti”.

An authentic and unmissable refuge where we stopped during our mountain bike crossing of the Assietta with my friend. Two incredible days filled with the beauty of the surroundings and exceptional autumn light. One night at 2500m altitude at the Casa Assietta refuge, where we were welcomed like royalty by Roberto! A good night's sleep under the covers after the host had prepared an excellent dinner for us! Thank you, Roberto!

From Colle dell'Assietta, you climb 1.5 km of rougher dirt road to Gran Serin, and from there you descend towards the barracks. It's an incredible place, thinking about how these structures were built. The road down to Frais is particularly rough, and the gravel is very difficult to navigate, but the views over the valley are breathtaking (if it weren't for the highway viaducts that block the view at the bottom of the valley).

The gravel routes directly around Exilles are generally classified as difficult due to significant elevation changes and technical sections, making them less suitable for young families or beginners. However, the broader Susa Valley and nearby natural parks like Parco Naturale Gran Bosco di Salbertrand might offer easier paths for family cycling, though these may not be specifically gravel-focused.
While many outdoor areas in Italy are dog-friendly, it's essential to consider the difficulty and terrain of these specific gravel routes. The challenging nature and potential for remote sections mean your dog should be fit and accustomed to long distances and varied surfaces. Always keep dogs on a leash, especially in protected areas like Parco Naturale Orsiera Rocciavrè, to protect wildlife. Carry enough water for both yourself and your pet.
Parking is generally available in the villages that serve as starting points for these routes, such as Sauze d'Oulx or Chiomonte. Look for designated parking areas within these towns.

While the high-alpine military roads can be quite remote, you'll find opportunities for refreshments in the villages at the start and end of routes, such as Sauze d'Oulx, Bardonecchia, or Usseaux. Some routes might pass by mountain huts (rifugi) like Rifugio Scarfiotti or Assietta Refuge, which often offer food and drink during the open season. Always carry sufficient supplies, as services can be sparse on longer, more remote sections.
