Day 2 of the Clifton Diocesan and the CA Pilgrimage to Lourdes: A walkthrough the Basilica of Saint Pius X during the International Mass.
Situated at the heart of the Sanctuary of Our Lady of Lourdes, the Basilica of Saint Pius X is one of the most impressive religious buildings in the Marian town. Almost entirely underground, this immense basilica can accommodate around 25,000 pilgrims during major celebrations.
Consecrated in 1958, its unique curved concrete ceiling resembles an upside-down boat, allowing the huge open space without interior pillars blocking the view.
Built to mark the centenary of the apparitions of the Virgin Mary to Saint Bernadette Soubirous, it is distinguished as much by its history and spiritual purpose as by the technical feats required for its construction.
Unlike the other religious buildings visible from the esplanade, it was built underground in order to provide a space large enough to accommodate the crowds of pilgrims.
It is used in particular for major international celebrations, when several thousand worshippers from all over the world gather in Lourdes.
