Historical and architectural monument, the medieval fortress of Deva (Hungarian: Déva vára, German: Diemricher Burg) was built in the middle of the 13th century on the Citadel Hill, a volcanic cone with an altitude of 378 m. With its special strategic position, the fortress guarded from the height that dominates the city of Deva for centuries, the exit and the entrance to Transylvania on the valley of Mureş. Here there have been found traces of Neolithic and Bronze Age, and the presence of carved stone blocks with the features of dovetail tail cuts makes archaeologists insight the remains of a Dacian fortification.
