Being in nature is sometimes a trip back to history, while in 1998 I used to climb on Mangart mountain in the Julian Alps of Slovenia together with my girl-friend. The trail at some parts is leading directly on the border between Italy and Slovenia (on the photo the white stone with numbers indicates the actual frontier).
Today this means a place of peace and challenge for those climbing on the mountains, but only 100 years ago this was a location of battles and war because this area used to be the Isonzo frontline in World War I, and here the armies of Italy and the Austrian Empire were executing fierce, endless fighting in the mountains up to altitudes of more than 2,000 m.
Relicts of this war without real winner (old military paths, ruins, tunnels) can still be found at diverse scattered locations in both countries. Today only the sky is the limit here fortunately.
