Near the Bassa del Druos there are the ruins of a shelter and the Druos Battery, a defensive military gun emplacement in a cave of the Vallo Alpino. The artillery battery, realized with minimum investment in the mid-thirties, consisted of 4 100/17 howitzers captured from the Austrians in WWI. The guns were positioned in the cave without any shielding whatsoever: there wasn't even a command room inside. Two of the 4 galleries where the cannons were placed can still be seen clearly, but the entrances to the other two have been obstructed by landslides.
