At the establishment of the French Protectorate over Morocco in 1912 the house became the regional headquarters of the Service des Arts indigènes ("Service/Office of the Native Arts"), which oversaw the study and preservation of historic heritage, under the direction of Alfred Bel at the time.[1] Its ground floor also served as the first Museum of Native Arts (Musée d'Arts indigènes), before this role was transferred to Dar Batha (the current historic art museum of Fes) in 1915.[1][2] The house continued to serve as an office for this agency under its two subsequent directors, Prosper Ricard and Marcel Vicaire.[2] It later became a conservatory of Andalusian music before falling into neglect in the 1980s.[5][6][5][6]
