For this international conference, we wish to propose a study of maritime material culture and especially in onboard fur-niture, used in a personal and collective way, whose modalities of acquisitions are usually marginal. The work of Horden and Purcelle (2000, 393) define port area like “nodes of density in the matrix of connectivity.” The analysis of archaeological artefacts, lost or rejected by vessels in anchorages, can characterise the structural diversity of ports present on the north-east coast Mediterranean during the post-medieval period and provides different level of maritime trade. Our analysis support is composed of ceramics produced between the XVIth and the XVIIth century coming from harbour dumpsite and shipwreck located on the north Mediterranean french coast. Think as one major archaeological artefact, ceramic may help to understand maritime exchanges, dishes and one part of the onboard instrumentum. The diachronic approach of this research leads to a repartition map of harbour dumpsite and shipwreck in north Mediterranean French coast. Confronted with written sources the results give us valuable information on relations and uses in north Mediterranean and allow us to better understand the everyday life seafarers.
