The historic port of Algiers, the subject of this research, bears witness to a great historical and typological wealth in terms of maritime heritage. Being an integral part of the major regeneration project of the Bay of Algiers, major socio-cultural and economic issues are linked to the choice of the degree of protection of the site's buildings. The objective of this research is to propose a participatory and sustainable approach for the classification of maritime legacies according to their type of protection in the urban regeneration process of the waterfront of the Bay of Algiers, in order to identify development strategies that respect both the spirit of the place and allow the social and economic development of the urban space.
