Athanaric's Wall, also called Lower Trajan's Wall or Southern Trajan's Wall, was a fortification line probably erected by Athanaric (the king of the Thervingi), between the banks of river Gerasius (modern Prut) and the Danube to the land of Taifali (modern Oltenia). Most probably, Athanaric's Wall has reused the old Roman limes called Limes Transalutanus.
The Walls, which, three metres in height and two meters in thickness, with broad outer fosse and many remains of forts, stretch in two almost parallel lines ... from the Pruth to the Dniester ... may be also Roman.
It stretches from Romania Buciumeni-Tiganesti-Tapu to Stoicani and after that it enters Moldova. In southern Moldova, it stretches another 126 km from the village of Vadul lui Isac in the Cahul District by the Prut River, and then goes into Ukraine ending at Lake Sasyk by Tatarbunar.
Some historians think that the southern Trajan Wall reached the city of Tyras, when was annexed by emperor Nero. Indeed, a Roman bronze coin was found during excavations that discovered evidences of the original construction in the first century
Bondoc wrote that "[The Wall's] huge size means the need of considerable material and human resources, a condition that could be met only by the Roman Empire ... the period of time when it was built stretched from Constantine the Great to Valentinian I and Valens".
Some scholars, like Vasile Nedelciuc, argue that the turf Wall was built initially by the Romans during Nero rule from the Prut river to Tyras, even because it has a ditch facing north. He argues that later it was enlarged by Athanaric, but only until Sasyk lagoon.
