Ključ Fortress

Ključ's fortress stands above the town on the Sana and is associated with the final campaign against the medieval Bosnian kingdom. The municipality records that King Stjepan Tomašević sought refuge here in 1463 before surrendering to Ottoman forces and being taken to Jajce. Later Ottoman administration developed a nahija, kadiluk and captaincy; the Tabor fortifications belong to this subsequent history. This is Ključ in Bosanska Krajina, not the separate castle of the same name near Gacko.

Architecture & evidence

Restored Tabor towers

Tabor is the younger central part of Ključ's three-part complex. The municipality records restoration of two towers in 2009. This model distinguishes their roofed forms from the medieval ruins.

Medieval ridge remains

The older settlement and palace occupied a constrained rocky site above the Sana. Low walls and foundations here express the surviving remains; vanished residential storeys are omitted.

Ljubica outwork

The separate fifteenth-century Ljubica tower provided flanking defense and observation. This study shows a reduced polygonal shell; its exact elevation and relation to the ridge are approximate.
