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.

This tower is part of the city's old medieval fortifications. It can be reached either by a fairly good (but fairly straight) dirt road from the east side, or by the paved Via Tur d'Amun and a short dirt section. Behind the tower, archaeological excavations have uncovered the ancient structures of the defensive complex (the excavation site is currently closed for construction [August 2025]). The view of Bardonecchia and the surrounding mountains is stunning.

The interesting exhibition would be even better if you understood Italian. It is still worth it because you are guided through the entire fortress and can explore it.

Tallest military fort in Europe. The climb is long and tiring and very crowded in the months of July-August but once at the top every effort is rewarded
