The building was initially erected in the early 1950s as the seat of the Legislative Assembly of the Tangier International Zone.
[1] Following the independence of Morocco in 1956 and its proclamation as a kingdom on 14 August 1957, the building was repurposed as a property of the Monarchy.

Participants in the Tangier Conference included Ferhat Abbas, Abdelhafid Boussouf, and Abdelhamid Mehri from the FLN; Bahi Ladgham, Ahmed Tlili, and Abdelhamid Chaker from the Tunisian Neo Destour party; and Allal al-Fassi, Ahmed Balafrej, Abderrahim Bouabid, and Mehdi Ben Barka from the Moroccan Istiqlal Party.
