The Limes Alutanus was a fortified line of the earlier eastern border of the ancient Roman province of Dacia and built by the Roman emperor Hadrian to stop invasions and raids from the east.[1]
It also included a vallum, built in the North-South direction, on the eastern side of the Olt river (Latin Alutus).
At least 12, and up to 16, forts are recorded on the Tabula Peutingeriana most of which have been confirmed by archaeological research, starting from the north:[2][3][4]
