Fun Fact (from this map nerd): I just realized the river that runs through old town Ljubljana is the same river that runs through Zagreb… the Sava river!
Bonus Fun Fact: The Sava river originates in the foothills of the Julian Alps near the Italy/Slovenia/Austria border and joins the mighty Danube in Belgrade, Serbia. Here the Danube continues east splitting Romania to the north and Bulgaria to the south until it finally spills into the Black Sea.
