In Maghrebi popular culture, Lalla Ghriba ('Strange Lady') is a legend and a myth about a woman who was a saint.
According to tradition, she appears at night in the El Korran neighborhood, her white ghost moving between houses, prophesying misfortunes to come for their inhabitants.
[1][2] Another mosque in Fes, Morocco, and a synagogue in Djerba, Tunisia, also bear the name of this mythical figure.
[3][4] The French researcher Charles Brosselard mentioned the existence of a plaque written in Maghrebi script, composed of 32 lines, describing all the properties and endowments (waqf) such as houses, shops, and books allocated to the mosque to provide services or revenues.
The minaret, fashioned as a tower with a four-pitched tiled roof, is placed next to the prayer hall, slightly rising above it.
