Hundreds of thousands of young Catholics poured into a vast field on Rome’s outskirts Saturday for the weekend highlight of the Vatican’s 2025 Holy Year: an evening vigil, outdoor slumber party and morning Mass celebrated by Pope Leo XIV that marks his first big encounter with the next generation of Catholics.

Thousands of young people gathered in Rome to see Pope Leo, marking a significant event in his tenure. The pope addressed attendees from over 146 countries, encouraging them to persevere in faith and serve the poor.
