The Bergalei were a Gallic tribe dwelling in the Val Bregaglia during the Iron Age and the Roman period.
The ethnic name Bergalei appears to derive from the Gaulish stem for 'mountain, mount', *berga-.
[1] The Bergalei lived in the Val Bregaglia, near the settlements of Clavenna (Chiavenna) and Murus (Bondo).
[2][3] Their territory was located north of the Aneuniates, south of the Suanetes, west of the Rugusci.
Two votive inscriptions dedicated to the god Mercurius Cissonius attest of a Celtic influence.
