The mass of Pope Leo XIV that took place on Monday, November 9, in front of the Monument to the Spaniards, in the Buenos Aires neighborhood of Palermo, gathered more than 2.5 million people and became the largest religious celebration since the beginning of his papacy in May 2025.
According to data released by the Vatican and local organizers, the concentration of faithful extended along a corridor of almost three kilometers along Avenida del Libertador. The magnitude of the gathering surpassed the attendance of the masses that the Supreme Pontiff had previously celebrated in Rome and Madrid.
Thus, Argentina was the scene of the most significant religious event of Leo XIV since he assumed the highest authority of the Catholic Church.
