Every Good Friday in Trapani a centuries-old tradition representing the Passion and death of Christ is repeated: the twenty-four hours Procession of the Mysteries (Misteri). The Procession of the Mysteries (Misteri) of Trapani still arouses great emotion and excitement in town. The Mysteries are eighteen sculptural groups and two simulacra made between the 17th and 18th centuries.

All statues are placed upon a wooden structure (vara) and statues are generally made of silver with golden and coral decorations. The procession has Spanish origins: at first, it was managed by a religious confraternity, then each group was entrusted to a Maestranza (arts and crafts) which together in 1974 founded the Unione Maestranze.
