Triduum of Saint Leo IX

Four days of devotion between the Cathedral and the Church of San Leo

The Triduum of Saint Leo IX is one of the most cherished events in the religious calendar of Sessa Aurunca, a city in the province of Caserta, in the far north of Campania, just a few kilometers from the border with Lazio. Every year, in the first days of May, the community gathers around the icon of the Alsatian Pope, whom local tradition inextricably links to the city's history: four days of celebrations that connect the Basilica Cathedral of Saints Peter and Paul, the Church of San Leo, and the Church of the Annunziata.

It should not be confused with the spring patronal feast which, together with the Madonna Avvocata del Popolo, enlivens Sessa Aurunca with brass bands, illuminations, and grand public spectacles. The Triduum is a distinct celebration, more intimate and strictly devotional, promoted by the Accollatori di San Leone IX together with the Santa Maria del Popolo Parish and the Sant'Eustachio Parish.

The Translatio of the icon, the heart of the celebration

The most defining moment of the Triduum is the Translatio: the icon of Saint Leo IX leaves the Cathedral and is carried on shoulders to the Church of San Leo, where it remains for the central days of the celebration. At the end of the liturgical journey, the image returns to the Cathedral accompanied by the faithful in an evening procession that winds through the alleys of the medieval village. It is a simple and ancient gesture that symbolically repeats the bond between the saint and the two places of worship that guard his memory.

The Accollatori—the confraternity responsible for physically carrying the icon and overseeing the organization—are the same group that animates the most important devotional processions of the year in Sessa Aurunca, starting with those of Holy Week, famous throughout Campania for its nocturnal rites.

Saint Leo IX and Sessa Aurunca

• The Pope: Bruno of Egisheim, elected Pope in 1049 under the name Leo IX, was one of the great reformers of the 11th-century Church and a tireless traveler.
• The year 1053: After the defeat at Civitate against the Normans, local tradition holds that the Pope stayed in Sessa; this episode supposedly led to the construction of the Church of San Leo, historically linked to the Abbey of Sant'Angelo in Formis.
• The relics: The Cathedral preserves relics attributed to the saint, some of which are inserted into the base of the 19th-century statue.
• The patronage: Saint Leo IX is the patron saint of the city and the Diocese of Sessa Aurunca; his liturgical memorial falls on April 19th, while the diocesan solemnity is set for May 8th.

A heritage to discover around the festival

Those who come to Sessa Aurunca for the Triduum find much more than a religious celebration. The Basilica Cathedral of Saints Peter and Paul, begun in 1113 and consecrated in 1183, is one of the most remarkable Romanesque monuments in Campania: the portico, the rose window, the eighteen reused columns from the ancient Suessa, the ambo, and the paschal candlestick attributed to the sculptor Pellegrino form a collection of rare quality. Not far away, the Church of San Leo has revealed, through excavations started in 2016, wall paintings dating between the 11th and 13th centuries.

The historic center, perched on the slopes of the extinct volcano of Roccamonfina, preserves the ducal castle, the Roman theater, and the Aurunci bridge: a setting that makes the visit interesting even for those not participating in the liturgies.

How to experience the Triduum

The atmosphere is one of authentic popular devotion, without spectacular scenography: bells, chants, the slow pace of the procession, and families stepping out of their homes as the icon passes by. The celebrations take place mostly in the late afternoon and evening, when the light on the Auruncian village is at its best. All functions are open to anyone who wishes to participate, without tickets or reservations: simply respect the liturgical nature of the moments in the church.
