Abusina

Abusina was a 3rd century Roman castra (military outpost) of the Roman Province of Germania. It was at Eining near Abensberg, on the Limes Germanicus, which at this point was the Danube River.

In the 2nd century the fort was occupied by the Cohors IV Tungrorum with about 1000 men. By the later Roman Empire archaeology and the  Notitia dignitatum suggest the site was occupied by Cohors III Brittonum with only 50 men.
