Trapani Mysteries Procession, on Good Friday, is a complex sequence of events that, for four hundred years, has kept intact its spiritual value and the deep link between the procession and the city, although changing its external and spectacular component. The Holy Procession, composed of 20 religious groups, starts at 2:00 PM on Good Friday and ends twenty-four hours later. It is considered as the longest Italian religious event, after Sant’Efisio festival which lasts about 4 days. The Holy Procession starts from the Church of the Purgatory Souls and it covers the main streets of the city.
