Located at the beginning of the long climb to Monfol, this evocative place, recently restored, was the ancestor of the refrigerator! Taking advantage of the winter frost, teams of men in the middle of winter extracted ice from the lake, to then store the blocks in the icehouse below, which was nothing more than an underground structure, insulated from the outside by a thick layer of earth with insulating properties, and capable of keeping the ice during the summer months.

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.

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”.
