Pope Leo XIV is set to celebrate Mass on Wednesday, November 11, at the Basilica of Our Lady of Lujan, Argentina's most important Marian shrine, in the last public event of his visit to the country.

The Mass will take place in the square in front of the basilica, about 70 kilometres west of Buenos Aires.

The celebration is expected to draw tens of thousands of pilgrims and Catholics from across Argentina, as the pope visits one of the country's most important centres of religious devotion.

The pope's visit to Argentina runs from November 8 to 11, with several public events scheduled across the country.
