BATAVA CASTRA(Passau), also called Batavinum oppidum, a town or rather a fort in Vindelicia, at the point where the Aenus flows into the Danube, and opposite the town of Boiodurum. It derived its name from the fact that the ninth Batavian cohort was stationed there. (Eugipp. Vit. Sever. 22. and 27; Notit. Imper. )
