The rock sculpture of Decebalus is a colossal carving of the face of Decebalus, the last king of Dacia, who fought against the Roman emperors Domitian and Trajan to preserve the independence of his country, which corresponds to present-day Romania.

Decebalus, sometimes referred to as Diurpaneus, was the last Dacian king. He is famous for fighting three wars, with varying success, against the Roman Empire under two emperors. After raiding south across the Danube, he defeated a Roman invasion in the reign of Domitian, securing a period of independence during which Decebalus consolidated his rule.
