Herzegovina Source of Buna Mostar

The source/spring of Buna River. The source of river Buna is at the foot of the hill, overlooked by a steep cliff.
Photo was taken from the terrace of Tekija - former Muslim monastery - built adjacent to the cliff. View towards SE.
River Buna is a short but water-plentiful left-bank tributary of Neretva south of Mostar. The source of river Buna is a kind of natural phenomena, since the river springs up in full strength beneath a steep cliff. It is a kind of those underground rivers common in a kras/karst terrain, which go underground at some point and resurface somewhere else. There are many identical photographs published.
