Not many things grow in the barren, rocky landscape of Hercegovina, but century-old fortresses seem to do well. Fortress Strac near the city of Trebinje is one of them. Semi-decayed, semi-buried in the earth, this Austro-Hungarian fortress is the defining feature of the landscape. The rocks, the hills, and the levels of stone walls rising out of hilly rocks – the view manages to resemble a scene deep out of the Middle East or Northern Africa… all without leaving Europe.
