Roman Castle Abusina

Abusina or Abusena was a Roman castra (military outpost), and later vicus of town, of the Roman Province of Raetia. The location is a few miles west of the Castra Regina (Regensburg). It was at Eining near Abensberg, on the Upper German- Raetian Limes, which at this point was the Danube River. The outpost was originally built out of earth and timber by cohors IV Gallorum in 79-81. The fortress was later rebuilt in stone during Antoninus Pius reign. Abusina stood near to the eastern termination of the high road which ran from the Roman military station Vindonissa on the Aar to the Danube. It guarded a bridge used by legions that may have often passed to guard the "limes imperii". In the 2nd century the fort was occupied by the Cohors IV Tungrorum with about 1,000 men. By the later Roman Empire, archaeology and the Notitia Dignitatum suggest the site was occupied by Cohors III Brittonum with only 50 men. In 233, it was sacked by the Alemanni and was abandoned by 254. It was reoccupied in 280.
