  Dacians had developed the murus dacicus (double-skinned ashlar-masonry with rubble fill and tie beams) characteristic to their complexes of fortified cities, like their capital Sarmizegetusa Regia in what is today Hunedoara County, Romania. This type of wall has been discovered not only in the Dacian citadel of the Orastie mountains, but also in those at Covasna, Breaza near Făgăraș, Tilișca near Sibiu, Căpâlna in the Sebeș valley, Bănița not far from Petroșani, and Piatra Craivii to the north of Alba Iulia. The degree of their urban development was displayed on Trajan's Column and in the account of how Sarmizegetusa Regia was defeated by the Romans. The Romans were given by treachery the locations of aqueducts and pipelines of the Dacian capital, only after destroying the water supply being able to end the long siege of Sarmisegetuza.
