Optatiana was a fort in the Roman province of Dacia. The ruins are located on the left bank of Almaș river, in the village of Sutoru.[2]
It was located on the former road between Napoca and Largiana/Porolissum and like the other forts of Limes Porolissensis it was constructed in two phases: an initial wood and earth structure, and a second one from stone.[3] During the second phase it reached a size of 165x 200m. It is possible that numerus Mauretorum was stationed at the location.[3]
