Blagaj Fortress

Blagaj Fortress or Old Town of Blagaj, locally known as Stjepan-grad, or Stipan-grad, in classical times Bona, is a town-fortress complex near the town of Blagaj [1]. The old Blagaj Fort was built on a high, inaccessible karst hill [1]. Remains of fortifications were discovered on each of the summit's highest points: On the north-eastern summit, there are the remains of a Roman or late antique fortification or observation post known as Mala gradina, while on the south-eastern summit the contours of a prehistoric hillfort can be discerned [1]. The south-western summit contains the remains of the present day Stjepan grad, a medieval or Ottoman period fort [1]. The ground plan of the fort is an irregular polygon adapted to the configuration of the terrain [1]. The walls of 12 or 14 metres in height have remained largely preserved, and range in thickness from 1.5 to 2.0 metres, while on the south they are no thicker than 1.5 metres [1].
