Maponos (“Great Son”) is mentioned in Gaul at Bourbonne-les-Bains (CIL 13, 05924) and at Chamalières (RIG L-100) but is attested chiefly in the north of Britain at Brampton, Corbridge (ancient Coria), Ribchester (In antiquity, Bremetenacum Veteranorum) and Chesterholm (in antiquity, Vindolanda).
No direct evidence exists of which military units may have been stationed at the fort, but it is likely that an auxilliary unit from Bremetenacum Veteranorum (Ribchester) would have been posted here.
