of research carried for a Masters degree. It was carried out with the aim to detect, understand their

geographical position, identify the construction techniques of the "cuves à salaisons" and define the

function of such sites. Fieldwork has enabled three different emplacements for salt-fish workshops to be identified : beaches, low coastal plateau and finally cliff-tops. All the sites studied present common

elements necessary for an efficient production : beaches, the proximity of running water and the sea.

Concerning the different elements of construction they all present specific characteristics. It has not been possible to reconsider the precise periods within which these workshops functioned due to the absence of datable chrono cultural material. However it is can be considered that they functioned from the end of the 1st century AD up to the middle of the 3rd century AD.
