Colonia Ulpia Traiana Augusta Dacica was the capital and the largest city of Roman Dacia, later named Ulpia Traiana Sarmizegetusa after the former Dacian capital, located some 40 km away. The city was destroyed by the Goths.

Today Ulpia Traiana remains in ruins, with a partly conserved forum, an amphitheatre, and remnants of several temples.
