Moldova
The remnants in Moldova comprise earthen walls and palisades. There are two major fragments preserved in Moldova: Upper Trajan's Wall and Southern (or Lower) Trajan's Wall.
The Southern Trajan's Wall in Moldova is thought to be dated by the 3rd century, and built by Athanaric and stretches from Romania Buciumeni- Tiganesti-Tapu-Stoicani and in after that another 126 km from the village of Vadul in Kagul Region by the Prut River stretches into Ukraine and ends at Lake Sasyk by Tatarbunar. The Coat of Arms of Cagul uyezd of Bessarabia, Russian Empire, incorporated Trajan's Wall. Some academics like Dorel Bondoc think that it was done by the Romans, because -to be done- it required plenty of knowledge and workforce that barbarians like Athanaric did not have.
The Upper Trajan's Wall is thought to be constructed in 4th century by Greuthungi Goths in order to defend the border against the Huns. It stretches 120 km from Dniester River by Kitkany in Teleneshty Region to Prut River and exetend till Tiganesti Sendreni in Romania.
Fragments of Trajan's Wall are also found by Leova.
