The Brigantii (Gaulish: Brigantioi, 'the eminent, high ones') were a Gallic tribe who lived southeast of Lake Constance (Lacus Brigantinus), in the area of present-day Bregenz (Brigantion), in Austria's state of Vorarlberg, during the Roman era.
[1][2] An identification with the Brixentes, a tribe listed on the Tropaeum Alpium, has been proposed by Ernst Meyer.
It derives from the stem briganti-, meaning 'high, elevated', which can be compared with the name of their chief town Brigantion ('eminence'; Latin Brigantium), also attested in other toponyms at the origin of the modern Briançon, Brégançon and Briantes.
The settlement was located on the northeastern bay of Lake Constance, at an intersection of important east–west and north–south traffic routes.
Late La Tène finds from the Ölrain plateau suggest the existence of a pre-Roman oppidum in the upper part of town.
