Pope Leo XIV held an open-air Mass in Paris. It took place on Saturday September 26 on the Champs-Élysées.

Pope Leo is a 71-year-old American. The Vatican estimated that 700,000 people attended.

ABC News reported the same figure. But France 24 estimated about 600,000 attended.

More than 600,000 people had registered before the Mass reports say. The Mass happened during Pope Leo's visit to France.

It was the first official papal visit in 18 years. A day earlier about 80,000 young people attended a vigil. The vigil took place at Stade de France near Paris.
