The St. George Fortress is strategically located above the valley of the river Mirna and the Pišine port on the river. Today it is only a ruin, but its ramparts are well preserved. Here used to be a medieval town, which is today preserved only in the archaeological traces and ruins of the church of St. George. This place has probably been inhabited since prehistoric times. The owners of the castle changed frequently, especially after the attacks of the Venetians in the 13th century and the Genoese in the 14th century when the fort lost its political and military role.
