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.[1]
