One of the most imposing military shrines, a work of propaganda from the "ventennio" that sought to mythologize the First World War

We are in the heart of the First World War Isonzo Front, where thousands of soldiers from both sides met their death... places that should make us reflect

We are in the heart of the Great War's front line. The stage for the infamous 12 battles of the Isonzo. Thousands of Italian and Austro-Hungarian soldiers died here. Many testimonies of fortified lines are still in excellent condition. Places that should make us reflect.

https://www.komoot.com/it-it/tour/1092082077 Here we are immersed in the Karst, and the feeling is one of great tranquility, even though we are just a few hundred meters from the village. At the historic site of the Dolina dei Bersaglieri, we are immediately catapulted back in time, having to cross and follow trenches that lead to the small basin of the famous First Aid Post of the Great War, now an open-air war museum. The route is very easy, on paved and dirt roads, with very little elevation gain and a high level of interest. It's a shame about the very tall grass...

Memorial dedicated to the Sassari Brigade, known for its ferocity in combat which earned it the nickname "Dimonios" from its Austro-Hungarian enemies.

The monuments in this area remind us of the heroic deeds and the cruel and bloody battles fought here. Now we can enjoy the area, and I hope it will always be that way.
