He wrote: 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.

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 academics such as Dorel Bondoc think that the wall was built by the Romans, because it required a great deal of knowledge and a workforce that barbarians like Athanaric did not have.

[6] 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,[7] 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.
