Based on the critical inventory of more than five hundred clothing accessories from the southern-Alps discovered in the northern-Alps, the present work aims at characterising the role of the Golasecca civilisation in the growth of circulation networks linking up the western Mediterranean to Celtic civilisations. Personal belongings discovered in many alpine and transalpine settlements and burial places bear witness of a direct implication of the Golasecca culture in medium and long-distance trades. This implication results in phenomena of cultural mix, technological transfer and mixed nature population, that are perceptible in certain areas of the alpine massif as well as through some displacements and relatively long-time frequenting of the main Hallstattian local settlements of varied kind and status. As a phenomenon which is partly linked to the emergence of aristocratic societies, the circulating of luxurious objects and ornaments illustrates the fact that Gollasecca has been a major go-between in the trade and communication networks between Mediterranean cultures and Hallstatt chiefs.
