The Old Blagaj Fort (Duke Stjepan City) is the medieval building, which was the seat of Blagaj Prince Miroslav Hum, Duke Sandalj Hranić and Duke Stjepan Kosača. It has an irregular polygonal shape, with a treasury, the royal palace, prison, two wells, towers and residential buildings.
It lost its strategic importance and was finally abandoned in 1835. But if you decide to visit the Old Blagaj Fort, prepare yourself because there are no toilets, cafes, restaurants or guides.
