Th is took place between the late 3rd millennium and early 2nd millennium BCE, in the archaeological site of Carreço beach, in Viana do Castelo, using removable sinks excavated in schist, that were heated to enhance the process of evaporation of salt water. Th is type of sink is very common along the northern coast of the Iberian Peninsula. Other archaeological evidence of sea salt exploitation exists in the Areias Altas archaeological site in Porto, daring from the fi rst half of the 2nd millennium BCE. In this site ceramic containers have been found that are morphologically similar to those used for evaporation of salt water using the brine process or as moulds for salt in other prehistoric salt extraction contexts in Western and Eastern Europe. On the Northwest coast of the Iberian Peninsula there are also countless sinks dug into the rocks, morphologically similar to removable schist sinks. Observation of their manufacturing conditions reveals that these sinks were made by percussion, probably using stone hammers, and polished with rounded pebbles, which gave them rounded corners. Th e absence of evidence of the use of metallic artefacts to make these sinks suggest that they were made before the Iron Age, although they may have still been used during that period. Th e diff erent extraction methods may be related to climate changes that occurred during the 3rd millennium and 2nd millennium BCE.Ce texte fournit les premières preuves de l’exploitation de sel marin dans le Nord-Ouest de la pénin- sule Ibérique à l’âge du Bronze. La production du sel s’opérait sur le site archéologique de la plage de Carreço, à Viana do Castelo entre la fi n du IIIe et le début du IIe millénaire avant J.-C. et montre l’uti- lisation d’éviers amovibles creusés dans le schiste et chauff és pour renforcer le processus d’évaporation de l’eau salée. Ce type de puits est très courant sur la côte nord. D’autres preuves de l’exploitation du sel marin se trouvent sur le site archéologique d’Areias Altas à Porto pendant la première moitié du IIe millénaire avant J.-C. Sur ce site, des récipients en céramique, morphologiquement similaires à ceux utilisés pour l’évaporation de l’eau salée par le processus de saumure ou comme moules pour le sel, dans d’autres contextes préhistoriques d’extraction du sel en Europe occidentale et orientale, ont été trouvés. Sur la côte nord-ouest de l’Ibérie, on trouve également d’innombrables puits creusés dans la roche, morphologiquement semblables aux puits de schiste amovibles. Une observation de leurs conditions de fabrication a révélé qu’ils étaient fabriqués par percussion, probablement avec des marteaux en pierre, et polis avec des galets roulés, ce qui leur donne une forme de coins arrondis. Ainsi, l’absence de preuves d’artéfacts métalliques dans leur fabrication indique qu’ils seraient antérieurs à l’âge du Fer, bien qu’ils aient pu être utilisés durant cette période. Les diff érentes méthodes d’extraction peuvent être liées aux changements climatiques qui se sont produits au cours des IIIe et IIe millénaires avant J.-C.Esta publicação foi apoiada através do Financiamento Plurianual do Laboratório de Paisagens, Património e Território (Lab2PT), Ref.ª UID/04509/2020, financiado por fundos nacionais (PIDDAC) através da FCT/MCTES

However, there is evidence that this activity took place in the region at least between the late 3rd millennium, early 2nd millennium BCE. Data from two archaeological sites are presented and the so-called removable sinks and the sinks excavated in the rock are re-evaluated. Their execution techniques are also discussed. The data set was articulated with the natural and topographic conditions of the coast and the known climatic conditions for the time. They were also articulated with the occupation strategies during the Bronze Age

Neste trabalho apresentamos a Estrutura 15 do sítio arqueológico das Areias Altas. Trata-se de uma
estrutura do tipo “fossa”, aberta no substracto geológico, no interior da qual se registaram seis depósitos de
enchimento, entre os quais salientamos a presença de um depósito de conchas. Para além deste, os restantes
depósitos apresentam características muito distintas, verificando-se uma certa alternância entre depósitos onde
estão presentes materiais cerâmicos e líticos e depósitos estéreis, semelhantes ao substracto geológico local.
Do ponto de vista artefactual, a tipologia dos materiais cerâmicos remete para a primeira metade do II milénio
AC, sendo coincidente com as datações por radiocarbono das conchas. Considerando as especificidades da
formalização do contexto em que foi identificado o depósito, tentaremos questionar em que moldes podemos
interpretar a sua ocorrência. Gostaríamos de enfantizar a proximidade da estação com o mar e a possibilidade
de entender o conjunto de conchas para além de uma relação de subsistência imediata. Isto é, não sendo um
contexto de descarte, como nos sugere a formalização da sequência de enchimento da estrutura, em que outro
tipo de cenário podemos considerar a manipulação destes elementos marinhos?
ABSTRACT
In this paper, we present the findings from Structure 15 from the archaeological site of Areias Altas.
This was a pit-type feature that cut into the geological substrate and that revealed six types of fill, amongst
which was a shell deposit. The remaining fills had quite distinct characteristics, and this manifested as an alternation
between contexts with sherds and lithic material and then sterile deposits that were similar to the local
geological substrate. In terms of the artefactual evidence, the typology of the ceramic material dates back
to the first half of the 2nd millennium B.C., matching the radiocarbon dates on the shells. There is a formalization
to the way in which things were deposited, and we will question how best to interpret these circumstances.
We want to stress the proximity of the site to the sea, and the possibility of understanding this assemblage
of shells as something that was beyond the means of immediate subsistence. If we are not dealing with a
discard context, as suggested by the formalization of the structure-filling sequence, what other type of scenario
may be considered for the manipulation of maritime elements?

To this end, I will first revisit the old excavation with its original interpretation and then present the data recently achieved by preventive archaeology work. The contemporary research has found that this is a large pit site, with a particular material culture, deeply connected with the adjacent marine environment and dating from the first half of the 2nd millennium BC. In addition, I draw attention to the distinctive features that make of Areias Altas a unique site in the context of the Bronze Age of northern Portugal, and in particular those that give depth to its social dynamics: the identification of deposition practices and the possibility of salt production through artificial evaporation.
