The Fortification System

In the area of Adamello-Brenta there are a number of forts dating back to the First World War, built on the mountains between Lombardy and Trentino. Here on Passo Tonale, the natural border between Austria and Italy, the war known as the ‘White War’ was fought.  A mountain battle characterised by the climate and location and the arduous terrain.

Some of the forts can still be seen and house museums dedicated to the war. These are usually connected to the paths taken by the military, now abandoned but still visited by historians and those passionate about the mountain war.

The following shows a list of forts in this territory.


Opening hours

Forte di Corno d’Aola

This fort was built in 1900 above Ponte di Legno in the province of Brescia, and its purpose was to protect the Italian border. The building was eventually blown up by the Germans at the end of the Second World War. There are just a few remains which can be seen today and can be reached by taking the Cable car or chair lift to Valbione.

Forte Strino

Located on the road to Tonale just before the bridge over the Rio Strino. It dates back to 1861 and was built by the Austrians. It was forgotten about after the First World War and reciperated during the ninties. It now forms part of the network of museums containing war memorabilia and relics. There are guided tours here.

Forte Velon

This small fort is situated just below Forte Strino and is connected to it by a concrete staircase. Currently it is not possible to visit, but what remains can be seen from the main road to Tonale after Vermiglio.

Forte Zaccarana or Tonale This is the highest of all the forts (2096m) and was avantguard during the war. Built in 1900 the most modern methods of the time were used for its construction. The fort can be reached on foot from Vermiglio, or from just above Tonale (the path from Ospizio S Bartolomeo). It was made safe and secure in 2009 and parts of the interior can still be visited. From here there is a magnificent view of the Val di Sole.
Forte Mero This was the last fort to be built and it was constructed between 1911 and 1913. It was designated to observe and defend the nearby territory and was therefore not equipped with cannons but only machine guns. On some walls the colours used to camouflage it can still be seen. The fort can be reached on foot from Ospizio S Bartolomeo. In front of the fort there is an area where you can stop.
Forte Pozzi Alti or Presanella

This fort was built between 1906 and 1912 in the Vermiglio valley and is located opposite Forte Zaccarana. The fort was badly damaged during the war and ultimately demolished after the war in order to recuperate iron and other materials. In 2008 the ruins were made safe. Today it can be reached on foot by way of an 8 kilometre mule track from Velon (Vermiglio).
