Between 2013 and 2015, the Franco-Algerian excavation conducted on the Place des Martyrs in the lower Kasbah of Algiers (in partnership with the CNRA and INRAP), has notably delivered the occupation levels of the Turkish Regency of Algiers between 1518 and 1830. It is the life of traders, craftsmen and inhabitants until the eve of the French intervention in 1832 which can thus be appreciated thanks to the excavation of a part of the Ottoman souk. In these well preserved structures, many local or regional ceramics previously unknown and imported tablewares have been uncovered. During, the 18th century, the imports testify of exchanges with Catalonia and Valencia region, Tunis, Provence, Liguria and Tuscany, Saxony, Holland, China, Turkey and undoubtedly also Syria. The comparison of archaeological data from Western and Eastern Mediterranean sites with historical sources makes it possible to distinguish what belongs to a dominant Ottoman "culture" similar to the different provinces of this vast Empire. The interpretation of the data feeds the local history but also that of the whole Empire, it gives information on the patterns of consumption, on the trade networks and diffusion, on the relations maintained with Europe, on the strong influence of the port of Marseilles in the Ottoman trade and confirms the globalization of the exchanges in the Mediterranean between cosmopolitan port-cities during the 18th century.
