Lourdes receives more than six million pilgrims every year and is one of the most important Catholic pilgrimage sites in the world, featuring several important locations. The Grotto of Massabielle is the site of 18 Marian apparitions in 1858, reported by Bernadette Soubirous. Believers claim that on the ninth appearance, a healing spring appeared, which is now a major pilgrimage site. Pilgrims also favor the Basilica of the Immaculate Conception, above the grotto, and the Basilica of Our Lady of the Rosary, home to incredible mosaics. Finally, the massive underground Basilica of St. Pius X is a 20th-century addition that can hold around 25,000 people. Learn more: https://www.lourdes-france.org/
