Located at an altitude of 831 meters above sea level. the Valledrane Fort is a work that is part of the Giudicarie Barrage. Its objectives ranged from the entire extension of Lake Idro to the heights between Capovalle and Valvestino, on which the Italian-Austrian border and the first line of the Giudicarie front ran. Its guns intervened several times in the first days of the war, then this work too followed a fate common to others and was disarmed. After the conflict it was definitively abandoned by the Army.
The vegetation has recently been cleaned up and can be visited (very carefully) both inside and outside. During the course of history it has unfortunately been robbed of any "removable" part.
The fortification is one of the largest of its kind in Italy. It develops mainly in length, following the morphology of the ground with its contour lines and thus forming several steps (analogy with the Austrian work of Verle). The domes are therefore not arranged on the same floor but in groups of two, on three terraces with staggered floors.
Although it has not suffered damage due to the war, it has some damage, mostly due to the work of the recoverers. Almost all the access stairs to the upper floor and part of the same floor are missing. Along the perimeter there are still two caponiers (a third has been demolished) with a moat around it. The fort was also equipped with an observatory dome positioned on the same level as the two highest domes.
