LA GOULETTE — The statue of Our Lady of Trapani left the church of Saint Augustine and Saint Fidelis on Saturday, carried on a bier by about ten men, and moved through the streets of the old Sicilian quarter toward the port, where the fishing boats — dressed with flags for the occasion — received the blessing. The crowd that followed it was, as it has been for more than a century, not primarily Catholic.

The procession takes place every 15 August, the Catholic feast of the Assumption. In Tunisia it has acquired a second meaning that has almost entirely displaced the first: it marks the end of the swimming season.

How a Sicilian rite became a Tunisian calendar date

The origin is documented and specific. In January 1848 the Bey of Tunis granted land to Monsignor Sutter, Archbishop of Tunis, on which a place of worship could be built. The procession itself was launched at the start of the twentieth century by Italian immigrants from Trapani, in western Sicily, who had settled in the port town north of Tunis. Parish archives record the procession of 15 August 1909 as one of the most spectacular in La Goulette's history, with the statue leaving the church and travelling the streets as far as Tunis, accompanied by a band.

What made it durable was that Christians, Jews and Muslims all followed it. The Little Sicily quarter of La Goulette was a place where those communities lived on the same streets, and the procession became the town's collective annual event rather than one community's religious observance.

It disappeared abruptly in the early 1960s, as the Italian and Jewish populations of Tunisia left. It was revived a few years ago, and now draws visitors from southern Italy who charter buses and, in some cases, plan their Tunisian holidays around the date.

What survives, and what is being asked of it

The phrase Tunisians actually use is about the sea. Currents change, waves get higher and rougher, jellyfish arrive; the received wisdom, passed from parent to child across generations with no religious content attached, is that after the Madonna goes out you do not swim.

That transmission is worth noticing on its own terms. A rite carried by a community that has almost entirely departed has been retained by the population that stayed, stripped of its doctrinal meaning and repurposed as a seasonal marker. It is one of the few surviving pieces of Tunisia's cosmopolitan port culture that is still practised rather than commemorated.

Writing in La Presse, Kamel Ghattas set against the folklore a practical warning from a lifeguard on the Raoued beach: the calendar is not what makes the sea dangerous, and treating 15 August as a safety rule is a mistake in both directions. Drownings after the date get explained away by the tradition; the civil protection warning flag, which is the actual signal, goes unwatched. His advice was the ordinary kind — do not swim when the red flag is up, avoid isolated stretches of beach where nobody would see you in difficulty, and remember that cold-water shock does not care how well you swim.

The heritage question

The revival has so far been sustained by the parish, by La Goulette residents and by Italian visitors rather than by any formal programme. Advocates of the procession's preservation, including those who have written about it as a symbol of religious coexistence, have argued that it deserves the same institutional treatment Tunisia has given other pieces of its plural heritage — documentation of the parish archives, restoration of the Little Sicily built environment, and inclusion in the cultural calendar the Ministry of Cultural Affairs publishes.

Sidi Bou Said's recent progress toward World Heritage recognition shows the state can move when a case is assembled. The Madonna of Trapani has the rarer quality of being a living practice rather than a preserved façade — and living practices are the ones that disappear quietly, as this one already did once.
