Stari grad Jajce
Stari grad Jajce is the following beautiful historical site on this list. The settlement of Jajce is located on a hill above the Pliva and Vrbas rivers' confluence. The main citadel, which fills the square space of the top of the hill, and the wall, whose shape is conditioned by the land arrangement, make up the fortification of the town of Jajce.
All of the buildings in the citadel have since been dismantled, leaving only the bastion in the southeast corner of the citadel, which replaced the former towers. The citadel's courtyard is thought to have been on the east side. The south side of the citadel has a secret entrance with a relief of the coat of arms, while the west wall has a secret entrance. The town's rampart, which runs along the river Pliva and begins at the southwest and northeast corners of the citadel, features two towers: a round Bear Tower and a drop tower below.
The second wall of the ramparts now has just two visible entrance towers, one near the Vrbas with a gate and the other below the citadel itself, which has been turned into a bastion. In the Middle Ages, it appears that this wall had two more towers.
