The Costești-Blidaru Dacian fortress is the ruin of a fortified town in the Orăștie Mountains, Romania [1] [2]. Built in the 1st century BC, it was one of the most powerful Dacian fortifications, designed to defend the region against Roman expansion [2]. The complex features massive stone walls and strategic watchtowers demonstrating advanced Dacian engineering [3] [4] [5]. Located near Costești village in Hunedoara County, it forms part of the UNESCO World Heritage Site of Dacian Fortresses of the Orăștie Mountains [1] [6].
