The Suetrii (Gaulish: *Su(p)etrioi, 'the good birds') or Suetri were a Gallic tribe dwelling around present-day Castellane (Alpes-de-Haute-Provence) during the Iron Age and the Roman period.
[7][8] Their chief town, Salinae (present-day Castellane), was founded during the Roman period and acquired its name after the local supply of salt.
It was situated on a trade road leading from Vintium (Vence), near the coast, to Dinia (Dignes), in the Alps, via Salinae and Sanitium (Senez).
[9][10] The exact location of the pre-Roman oppidum remains unknown, although it was most likely seated on one of the hills surrounding Salinae.
[9] They are mentioned by Pliny the Elder as one of the Alpine tribes conquered by Rome in 16–15 BC, and whose name was engraved on the Tropaeum Alpium.
