The sanctuary's foundation is linked to a 15th-century shipwreck off the coast of Sicily, which allegedly carried the icon of the Madonna.
The interior contains a 16th-century marble altar sculpted by local artists using the characteristic white Custonaci marble.
The sanctuary hosts the 'Living Nativity' (Presepe Vivente) in the nearby Mangiapane caves annually, which draws thousands of visitors.
The building was constructed to replace a smaller, older church that had become inadequate to house the growing number of pilgrims.
The painting of the Madonna di Custonaci is protected by a heavy silver frame added in later centuries due to its high religious significance.
The Santuario di Maria Santissima di Custonaci is a historic 16th-century sanctuary built upon the site of an older medieval chapel. It houses a revered oil-on-board painting of the Madonna di Custonaci, believed by local tradition to have been brought to Sicily by sailors fleeing Constantinople. The sanctuary's architecture reflects a blend of local limestone masonry and Renaissance structural elements. It serves as the primary pilgrimage destination for the local community, particularly during its feast days. The interior contains significant marble altars and votive offerings that span several centuries of regional history. The site sits in the heart of the town of Custonaci, known historically for its extensive marble quarries.
