Cannon Gallery

At the foot of the Tofana di Rozes, on the western slope, is the historic and extensive Cannon Gallery.

It was excavated by the Italian army after the conquest of the Castelletto, as a defence post and storehouse, as well as a shelter from the weather and enemy gunfire. 

The vastness of this gallery is astonishing: an underground complex with several windows and loopholes overlooking the Val Costeana, the Lagazuoi and the upper Val Travenanzes. 

Inside is an old cannon that was restored and then brought back with the help of a helicopter.

It is reached by leaving the car at the Dibona Hut, on the Falzarego Pass, and taking first path 403 and then path 404 right at the base of the Tofana di Rozes. 

Once you leave the Castelletto Tunnel on the right, which goes up by means of ladders, you continue on through some detrital rubble (poorly marked path), the vent channel of the Castelletto mine explosion, and reach the Cannone Tunnel.
