In World War I, after crossing over Albania where it was annihilated, the Serbian Army recovered after a while and occupied its position at the Macedonian front, which spread across the mountain Kajmakčalan in Маcedonia. On the top of this mountain there was the observation post of the Serbian Army High Command.
This monument is located in a park near me, Pioneers Park, named for Tito's Pioneers Youth Movement. Here's a photo from this blog, where you can read more about them.
