Acidava (Acidaua) was a Dacian and later Roman town and fort on the Olt river near the lower Danube.[1] The settlement's remains are located in today's Enoşeşti, Olt County, Oltenia, Romania.Acidava was part of the Limes Alutanus, a line of fortifications built under emperor Hadrian running north–south along the Alutus (Olt) river.[2] The function of the limes was to monitor the Roxolani to the east and deter any possible attacks.The same document depicts a second Acidava, between Cedoniae and Apula, but some authors believe it is actually a copy error[5] and the correct name is Sacidava, another Dacian town.
