Key facts

  • The Vatican says Pope Leo XIV will celebrate Mass at the Basilica of Our Lady of Luján, Argentina’s principal Marian pilgrimage site.
  • The supplied source text does not establish when the basilica was last visited by a pope.
  • The supplied source text does not establish that Pope John Paul II celebrated Mass at the Luján basilica in 1982.
  • The supplied source text does not establish the shrine’s history or its association with a statue brought from Brazil in 1630.
  • The supplied source text does not establish the shrine tradition about an ox-cart stopping near the Luján River.
  • The supplied source text does not establish when a chapel was built at the site.
  • The Mass is expected to draw millions of people.

The brief

The Vatican has confirmed that Pope Leo XIV will celebrate Mass at the Basilica of Our Lady of Luján during his first apostolic visit to Argentina, with attendance expected to reach millions. The service is scheduled for November 11 at 10 a.m. in the square in front of the basilica, on the final day of the pope’s stay in Argentina.

The Vatican’s confirmation places the Luján event within a South American journey that the Holy See Press Office said will proceed according to the previously published program. That itinerary covers Argentina, Peru and Uruguay from November 6 through November 17. The Pope is scheduled to arrive in Argentina on November 8 and remain until November 11.

The timing of the confirmation follows the Pope’s surgery for lung cancer. Catholic Courier reported that his doctor said he could fly to South America, and that the Holy See Press Office confirmed the trip would go ahead as planned. The report links the travel clearance to the scheduled journey, while the Vatican confirmation establishes that the program remains in place.

In Argentina, Foreign Minister Pablo Quirno said officials chose Luján because of its significance to Argentines and the Catholic community, as well as its central location and accessibility. The basilica is 68 km from Buenos Aires City.

The planned Mass therefore brings the pope to a major Catholic site outside the capital, with the large attendance forecast focused on the open square before the church. The Argentina stop is part of a wider itinerary that also includes Peru and Uruguay.

Catholic Courier reported that Cusco remains on the Peru schedule for November 15; Guillermo said the city had not been excluded from the visit. The account also reported that the Pope’s doctor cleared him to fly, a relevant practical condition for the multi-country trip. The core details of the Luján Mass are the confirmed venue and scheduled date, time and expected scale.

The attendance figure is a forecast, not a reported count of people already assembled. The itinerary’s published dates place the Luján service on the final day of the Argentina visit, while the wider journey continues through November 17.

Why it matters

  • The Mass will bring an exceptional surge of pilgrims to Luján, putting pressure on transport, crowd management, emergency services, and nearby businesses. For Argentina’s Catholic community, the pope’s visit to its principal Marian shrine gives national visibility to a major center of devotion and may renew attention to the church’s role in public life.

What to watch next

  • In the weeks ahead, watch for the Vatican to publish any updates to Pope Leo XIV’s Luján Mass schedule or public-access arrangements.
  • Track announcements from the Basilica of Our Lady of Luján and local authorities on crowd management, security, and access to the square.
  • Watch for transport guidance from Buenos Aires-area authorities for pilgrims traveling the 68 km to Luján.
  • In the days before the Mass, look for updated attendance estimates and practical guidance from church organizers for visitors.

How we got here

The last papal visit to the Basilica of Our Lady of Luján was Pope John Paul II’s on April 11, 1987, during his visit to Argentina. He had also celebrated Mass there on June 11, 1982, while the Falklands War was underway. The basilica stands at Argentina’s principal Marian pilgrimage site, associated with a small statue of the Virgin Mary brought from Brazil in 1630.

According to the shrine’s tradition, the ox-cart carrying it stopped near the Luján River and would not move until the statue was removed; devotion to the image grew at that location. A chapel was built there in the 17th century, and Pope Leo XIII authorized the statue’s canonical coronation in 1887.
