History

The Dacians — a Thracian people who dominated the Carpathian basin from roughly the 1st century BC — chose the ridge above modern Grădiștea de Munte for their capital for reasons of defence and sanctity simultaneously. By the time of King Burebista (c. 82–44 BC), who briefly united Dacian tribes into a major power that alarmed Julius Caesar, the site had already assumed political importance. Under Decebalus it became the undisputed centre of the Dacian state: a grid of terraces cut into the hillside supported rectangular buildings interpreted as aristocratic residences, craft workshops, and storehouses, while the outer ring of stone walls with square towers enclosed an area large enough to sustain a substantial permanent population.

Decebalus’s success in defeating Roman forces in the 80s and 90s AD — forcing Emperor Domitian to pay tribute in 89 AD — made Trajan’s subsequent campaigns (101–102 and 105–106 AD) campaigns of personal prestige as much as strategic necessity. After the second campaign Trajan garrisoned Dacian territory as the new province of Dacia and founded a new Roman city, Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa, in the plain below — deliberately using a version of the original name to assert continuity and legitimacy. The original hilltop capital was left to ruin. Its systematic demolition means that little above foundation level survives, but the foundations themselves are extraordinarily complete.

Rediscovery was gradual: Romanian scholars began investigating the site in the 19th century, and systematic excavation began in the 1950s. A major ongoing problem is illegal metal-detector looting; the UNESCO designation and increased enforcement have helped, though the remoteness of the site makes policing difficult.
