Pope Leo has begun a four-day apostolic journey to France, with stops in Paris, Lourdes and Metz aimed at encouraging French society and the Church.
More than 80% of French people view him favorably, the Vatican envoy said, and registrations for major events in all three cities filled within days.
The visit comes as France faces economic strain, social-cohesion pressures and immigration tensions, issues the pope is expected to address with appeals for cooperation and hope.
Church officials also point to a rise in youth and adult baptisms and renewed interest in prayer, hoping the trip deepens that momentum into a broader Catholic revival.
Metz and UNESCO give the journey a wider European frame, linking Leo's message to Robert Schuman's legacy and to education, culture and peace.
