The historic site of the Old Blagaj Fort (Stjepan grad) - Unlike other fortifications serving as residences in Bosnia and Herzegovina, the Blagaj fortress is located on a natural level area above steep cliffs to the south, west and north. The walls have survived for much of their length to a height of 12 or 14 m. The interior defended area is relatively small, similar to that of the fortress in Jajce.
