Limes Alutanus

Limes Alutanus was a fortified line consisting of a vallum, built in the North-South direction, on the eastern side of the Olt river and seven roman castra, as is remembered by Tabula Peutingeriana. Limes Alutanus was the eastern border of the Roman province of Dacia.

The fortification was ordered by the Roman emperor Hadrian, in order to stop Eastern invasions.

The following seven castra positions were assumed by Romanian archeologist Vasile Pârvan, and later confirmed by archeological research. They are:
 * Pons Vetus (Câineni, Vâlcea)
 * Praetorium (Racovița, Vâlcea)
 * Arutela ("Poiana Bivolari" point, near Călimăneşti town)
 * Castra Traiana (Sânbotin, Vâlcea)
 * Buridava (Stolniceni, Vâlcea)
 * Pons Aluti (Ioneştii Govorei)
 * Rusidava (Drăgăşani)

Historian Adrian Blejan also adds these castra in his work, Dacia Felix:
 * Acidava (Enoşeşti)
 * Romula (Reşca)
 * Râul Vadului
 * Copăceni

On the Olt river at least other three castra exists:
 * (Cincșor) (Cincșor, Sibiu)
 * (Feldioara) (Feldioara, Sibiu)
 * Caput Stenarum (Boiţa, Sibiu)
