Pope Leo XIV celebrates Mass at Place de la Concorde before an estimated 800,000 faithful

PARIS — Pope Leo XIV led an open-air Mass at the Place de la Concorde on Saturday before an estimated crowd of more than 800,000 people, according to Vatican figures, in the centrepiece of the second day of his four-day apostolic visit to France. The service was staged beneath a giant white canopy erected as a makeshift altar, turning the square at the heart of the French capital into an improvised sanctuary on one of the most heavily secured days in the city's recent history.

The 71-year-old pontiff, the first American to sit in the papacy and the leader of the world's roughly 1.4 billion Catholics, arrived in the "popemobile" — the pope's open-topped, specially adapted vehicle — travelling down the Champs-Élysées before proceeding to the Concorde for the ceremony. He wore white liturgical vestments throughout. The trip is the first official papal visit to France in nearly two decades, and it is being held in a country that is constitutionally secular but whose history, politics and culture remain deeply interwoven with Catholicism.

The scale of the gathering stretched well beyond the square itself. The Vatican said some 800,000 people had assembled along a route of more than two kilometres, continuing past the Arc de Triomphe, as the popemobile made its slow procession through the crowd. Pilgrims, parishioners and plain curiosity-seekers packed the avenues, many having travelled from outside the capital and some from far beyond Europe.

Security around the event was extensive. The city centre was sealed off for the duration of the service, with helicopters circling overhead and snipers positioned on rooftops along the route and around the square — precautions reflecting both the scale of the crowd and the heightened alert surrounding a papal visit at a politically sensitive moment.

In his address, the pope struck a theme of unity and shared rejoicing. "It is truly good and pleasant when brothers and sisters come together and glorify the greatness of God," he said, according to the remarks delivered from the makeshift altar. The gathering itself was widely seen as the point of the day: in a nation where church attendance has declined sharply and where the role of religion in public life is regularly contested, a crowd of that size represented a striking assertion of Catholic visibility.

Among those in attendance was Aline Riziki, 41, who was born in the Democratic Republic of the Congo and has lived in France for 11 years. She described the experience as something that happens only once in a lifetime. "I dropped everything to come here and see him, to pray for peace in the east" of her homeland, she said, referring to a country wracked by conflict for decades. Her presence — like that of many others — underscored that the event drew not only French Catholics but members of France's large diaspora communities.

Other attendees emphasised the communal and familial dimension of the day. Jeanne de Montagnac, 29, came with her husband and their two-year-old daughter, who was perched on her father's shoulders and wore a small golden cross over her jumper. "We're happy that, even if she won't remember it, we're sharing this with her," she said. "It's an important moment for us to be surrounded by other people who also have faith." Her words captured a recurring sentiment throughout the crowd: the Mass was as much about belonging as about belief.

The visit has also been drawing large crowds outside the liturgical events. On Friday, an estimated 300,000 people turned out to see the pontiff as he waved from the popemobile while travelling to Notre Dame Cathedral. That procession drew comparisons with the enthusiasm surrounding John Paul II's celebrated visit to France more than four decades ago, a reference echoed by observers of the scene. François Mabille, director of a geopolitical observatory, said there was a sense of fervour reminiscent of that experienced over 40 years ago with John Paul II — a remark that suggests the visit has rekindled a public appetite for papal occasions that had largely faded.

The political subtext has been difficult to miss. The trip comes seven months before French voters choose a successor to centre-right President Emmanuel Macron, an election that the anti-immigration far right regards as its strongest opportunity yet to capture the presidency. Several presidential hopefuls were on hand for the Mass, including far-right leader Marine Le Pen and centrist Edouard Philippe. President Macron himself did not attend, but was represented by his wife, Brigitte Macron — a choice read by some as a reflection of the delicacy of a pope arriving in a country in the grip of a contested electoral season.

Earlier the same day, Leo met migrants at Maison Bakhita, an association supporting refugees, where he said it was "possible to encounter one another and to live together in dignity and peace." He also stressed the "fundamental role of women in building a civilisation of love." The association said the pope's visit sent a "message" ahead of the April–May election, a characterisation that places the migration encounter firmly within the campaign's fault lines on immigration and national identity.

The pope's itinerary also reaches back to one of Catholic France's most significant sites: the second day of the visit concluded with prayer at the Grotto of Massabielle in Lourdes, a renowned pilgrimage destination drawing Catholics from around the world, a location long associated with the Lourdes apparitions and the resulting influx of pilgrims.

On Sunday, the pope is due to meet seven victims of clerical sex abuse. That engagement carries particular weight in France, where a 2021 inquiry established that clergy or lay members of the Church had abused some 330,000 people as minors over a period of seven decades. The meeting follows decades of controversy over the Church's handling of abuse allegations in the country, and it will be watched closely for what it signals about the French hierarchy's willingness to face the issue publicly.

For the Vatican and the French Catholic establishment, the weekend delivered a demonstration of both reach and resonance. Whether the enthusiasm of the crowd translates into lasting change in a largely secular society is less certain; but as an image of institutional soft power, the sight of a vast crowd stretching beyond the Arc de Triomphe on Saturday is unlikely to be soon forgotten. As one pilgrim put it simply: "It's one time in history to see the pope."
