Called “Zwischenwerk Sommo”, Forte Sommo Alto was built on the upland with the same name, between 1911 and 1914, 1613 m above sea level.
The fort is divided in 3 floors, armed with two 10cm howitzers in a reinforced dome and an observatory tower. It was furnished with 18 machine gun posts for close defence.
Firstly designed to become a fortified barrack, it was turned into a fortress during the construction.
An embankment rather than a trench safeguarded it. The embankment monitored the val Orsara and Passo Coe together with Forte Dosso delle Somme.
Forte Sommo Alto was armoured with four emplacement accessible through underground tunnels, still walkable.
