Lourdes drew hundreds of thousands on Sunday as Pope Leo XIV led an open-air Mass after arriving from Paris and praying at the Massabielle Grotto the night before.
Seven clergy abuse victims were due to meet the pope during the visit, which aides and local church figures framed as a mission of purification, healing, repentance and accountability.
The pope also met bishops, the sick and Lourdes support staff, and was expected to see people whose recoveries the Church has recognized as miracles, including Sister Bernadette Moriau and Antonietta Raco.
The trip centers on Lourdes' dual role since Bernadette Soubirous reported 18 Marian visions there in 1858: a global pilgrimage site for physical cures and, more often, spiritual healing.
