Discover more about Basilica of St. Pius X

The Basilica of St. Pius X, often called the Underground Basilica, is a unique and awe-inspiring Catholic church located in Lourdes, France. As part of the Sanctuary of Our Lady of Lourdes, a major pilgrimage site, this basilica holds a special place in the hearts of millions who visit each year. Its construction was completed in 1958, coinciding with the centenary of the Marian apparitions to Saint Bernadette Soubirous, marking a significant milestone in the history of Lourdes. The basilica's origins lie in the vision of Bishop Pierre-Marie Théas, who sought to create a shelter for pilgrims during processions, especially in adverse weather. With the support of Pope Pius XII, a project was launched to construct an underground sanctuary capable of accommodating the massive crowds that flocked to Lourdes annually. The consecration was led by Cardinal Angelo Roncalli, later Pope John XXIII. Unlike traditional basilicas, the Basilica of St. Pius X is almost entirely subterranean, nestled beneath the esplanade of the sanctuaries. This architectural choice was driven by the need for a vast, unobstructed space to house the ever-growing number of pilgrims. The basilica can accommodate up to 25,000 people, making it one of the largest churches in the world by capacity. The sheer scale of the interior is breathtaking, offering a unique spiritual experience. The design, by architect Pierre Vago and engineer Eugène Freyssinet, is a marvel of modern engineering. The structure utilizes pre-stressed concrete to withstand the pressures of being underground, with the basilica located below the level of the Gave de Pau river. The nave is an oval shape, stretching 191 meters in length and 61 meters in width. The ceiling, though only 10 meters high, creates an expansive feel due to the clever arrangement of 29 concrete beams supported by 58 pillars, giving the impression of an upturned ship. The interior of the Basilica of St. Pius X is characterized by its minimalist aesthetic. The exposed concrete and sparse decorations direct attention to the spiritual essence of the space. Artificial lighting creates a serene ambiance, enhancing the sense of reverence. Suspended from the ceiling are 48 tapestries depicting saints and blessed figures from across history, symbolizing the universality of the Church. Along the walls, visitors can find 52 images in the gemmail style, a technique using overlapping stained glass to create vibrant and luminous artworks. These images include the Mysteries of the Rosary and the Stations of the Cross, offering pilgrims visual aids for contemplation and prayer. The series "Bernadette's Way of Light," based on sketches by René Margotton, depicts the 18 apparitions and scenes from Bernadette's life, further connecting the basilica to the story of Lourdes. The basilica also features an impressive organ, originally built in the Basque region of Spain and later restored after flood damage in 2013. The organ plays a central role in the ceremonies held within the basilica, filling the vast space with music and enhancing the spiritual atmosphere. Despite its modern design, the Basilica of St. Pius X has faced some criticism for its utilitarian appearance. Some have referred to it as a "spiritual bunker" due to its raw concrete construction. However, many find its simplicity and immensity to be deeply moving, creating an atmosphere of contemplation and prayer that transcends its architectural style. The basilica has faced challenges, including a significant flood in 2013 that inundated the space. However, it has persevered, undergoing restoration and continuing to serve as a vital center for pilgrimage and worship. The Basilica of St. Pius X stands as a testament to the enduring faith of those who visit Lourdes, offering a space for spiritual renewal and connection. Visiting the Basilica of St. Pius X offers a unique experience. The sheer scale of the underground space is awe-inspiring, and the minimalist design encourages contemplation. Whether attending a mass, participating in the Eucharistic procession, or simply exploring the space, visitors are sure to be moved by the basilica's spiritual atmosphere. The basilica is accessible to all, with ramps and facilities for those with reduced mobility, ensuring that everyone can participate in the ceremonies and experience the sacredness of the site. The Basilica of St. Pius X is more than just a church; it is a symbol of hope, faith, and community. Its unique architecture, vast capacity, and spiritual significance make it a must-see destination for anyone visiting Lourdes. It stands as a reminder of the history of the Marian apparitions and the enduring power of faith that continues to draw millions of people to this sacred town each year.
