It preserves vivid traces of the Muslim settlement which, starting in 846 AD, transformed the ancient Norman village into a political and cultural stronghold called Qalʿat an-nisāʾ, “castle of women.” Enclosed between Via delle Medaglie d’Oro, Via San Domenico, and Via Santa Domenica, it covers an area of 177,067 m². Walking through its paved alleys, characterized by inner courtyards and low roofs, visitors retrace the typical morphology of Islamic urbanism: houses built closely together to protect against the summer heat, narrow passages that channel breezes, and hanging courtyards where Berbers once cultivated citrus fruits and vegetables for self-sufficiency. At the heart of the quarter stands the Church of San Domenico, built in the mid-1400s, which preserves within its walls arabesque stone curtains reused from the Gothic structure, while artisan workshops and old “low houses” display portals of rusticated ashlars and windows with hand-forged iron grilles. Every year, between Christmas and Epiphany, the living nativity scene of Caltanissetta enlivens the quarter with around 150 costumed figures who re-create, among the houses and alleys, scenes of ancient Palestinian crafts but with a Sicilian imprint (from the cicerara to the lavannara), reviving an anthropological heritage at risk of being lost. Supported by the Municipality and local associations, this event turns the quarter into a vast open-air stage, restoring to the community the memory of its origins and promoting slow tourism in search of Caltanissetta’s Arab-rooted identity.
