Mengore hill, together with the two neighbouring hills, Cvetje and Bučenica, was the core of the Austro-Hungarian defence of the Tolmin bridgehead. The entire area was strongly fortified with numerous trenches and caves. All the time during the 29 months of the war, the Austro-Hungarian positions on Mengore hill were exposed to constant shelling by the Italian artillery from higher elevations on the right bank of the Soča. Neither side attained any bigger success. It was exactly this area that served in the decisive 12th Isonzo Battle as the point of departure for the successful breakthrough of the joint Austro-Hungarian-German Army, which pushed the Italian troops from the Upper Soča Region all to the river Piave.
A circular path through the museum runs past well-preserved and restored remains of the Austro-Hungarian first line of defence. It runs past trenches, caves, memorial tablets, remains of stone walls of cabins, a water reservoir and the monument of the onetime military cemetery. On the top of Mengore hill stands a church, dedicated to the Virgin Mary's name.
