The hill of Spig/Špik north of the monastery on Castelmonte/Stara gora was part of the fourth line of defence of the Italian Army. The top of Mt. Spig was turned into a base from where the Italian soldiers had a survey over the accesses from the Valli del Natisone/Nadiža valleys towards Cividale del Friuli/Čedad and further towards the Friuli lowlands. The well-fortified positions were used only in the Twelfth Isonzo Battle. After fierce combats, the advancing German troops conquered it on 27 October 1917, and also captured 2,000 Italian soldiers.

Recommended is access from the hamlet Trivio Spik where you can park your car and continue towards Castelmonte/Stara gora on foot. After 300 metres, the footpath to Mt. Spig/Špik starts on the left. Most of World War I remains can be seen along the trail up to the top. Once reaching it, you return along the same path to the starting point.
