On Wednesday, Pope Leo XIV will embark on a landmark day of religious and cultural engagement during his seven-day trip to Spain, bringing together a millennium of Catholic heritage and modern global faith at two of Catalonia’s most iconic sites: the mountain-top medieval Benedictine monastery of Montserrat and Barcelona’s world-famous Sagrada Familia Basilica.
Nestled a short drive outside Barcelona atop a steep, rugged slope, Montserrat holds a deeply cherished place in the cultural and spiritual identity of Catalonia’s people. Each year, more than 2 million pilgrims and travelers journey to the 11th-century abbey complex, which also houses a 16th-century basilica and the revered Black Madonna statue. While historical analysis confirms the carving was originally white, centuries of exposure to candle smoke and incense darkened its surface before it was repainted black, cementing its status as a beloved symbol of faith for locals. For Catalans, Montserrat is far more than a religious site: it is a core pillar of regional culture, tied closely to efforts to preserve the Catalan language and centuries-old traditions. As Catalan theologian Francesc Torralba explained, many Catalans turn to the Black Madonna in times of hardship, calling the mountain a spiritual home for the region.
For global observers, however, the undisputed highlight of the Pope’s visit will be his evening Mass at the Sagrada Familia, held to mark 100 years since the death of the basilica’s visionary architect, Antoni Gaudí. During the trip, Pope Leo will deliver nearly all remarks in Spanish, with select addresses in Catalan, reflecting a careful balance of national and regional outreach.
Unlike most of Europe’s ancient cathedrals, the Sagrada Familia’s enduring global allure stems from its one-of-a-kind design and ongoing construction. Work first began on the site in 1882, during the papacy of Leo XIII — Pope Leo XIV’s namesake — and continues to this day, funded entirely by visitor entrance fees. Gaudí’s masterpiece blends natural imagery — from towering tree-like columns and carved birds to abundant fruit motifs — with narrative scenes from the life of Jesus Christ, creating a space that bridges 2,000 years of Christian history with modern and postmodern design sensibilities. As Ferran Sáez, a humanities professor at Barcelona’s University of Ramón Llull, notes, the building communicates complex theological ideas in an accessible way that resonates with believers and non-believers alike.
Today, the Sagrada Familia tops nearly every international traveler’s bucket list, with foreigners making up 90% of its annual visitor base — and more Americans visiting than Spanish nationals. Its recent completion of the Tower of Jesus Christ earned it the title of the world’s tallest church, drawing even more attention, and it has proven remarkably popular with adolescents and young adults, a stark contrast to the aging parishioner base of most traditional Spanish churches, at a time when the global Catholic Church is working to re-engage younger generations.
Pope Leo’s visit comes at a moment of profound religious shift in Spain, and particularly in Catalonia, one of the country’s most secular regions. Following Spain’s transition to democracy in the late 20th century, religious adherence has declined steadily: a 2024 state poll found just over half of Spaniards identify as Catholic, and only one in five of those are practicing believers. Unlike more religious regions of Spain such as Seville, Catalonia’s Catholic tradition is understated, focused on sacred sites rather than large public processions. In this context, the Pope’s dual visit to Montserrat and the Sagrada Familia represents a deliberate balancing act: upholding centuries of religious tradition in a rapidly secularizing society, while using the Sagrada Familia’s global profile to reach audiences far beyond Spain’s borders.
What many visitors and even locals do not know is that the two sites share a hidden historical connection. According to Mònica Santín, a tour guide, historian, and doctoral candidate researching Gaudí, the young architect got his early training working on a Montserrat chapel project for the original architect tapped to design the Sagrada Familia. When that architect’s neo-Gothic plan proved too costly to execute, the commission passed to Gaudí, who wove elements of Montserrat into his iconic design: the basilica’s distinctive soaring towers echo the jagged, spire-like rock formations of the Montserrat range, leading Santín to call the Sagrada Familia “a Montserrat in the middle of the city.”
For all its cultural and spiritual significance, the Sagrada Familia’s global fame has also created frictions. Many Barcelona residents blame the basilica’s popularity for worsening overtourism in the surrounding neighborhood: cruise ship day-trippers flood local streets, the area is dominated by chain fast-food outlets and souvenir shops, and tensions boiled over last year when water gun-wielding protesters targeting mass tourism were stopped by police before they could reach the basilica. Sagrada Familia rector Rev. Josep Turull acknowledges the inevitable friction between locals and tourists, but frames growing pains as an opportunity for improvement, noting the basilica works to ensure local parishioners still feel it is their spiritual home even as it welcomes millions of global visitors.
Basilica construction CEO Xavier Martínez projects that Pope Leo’s Mass will drive a similar surge in visits to the one that followed Pope Benedict XVI’s 2010 consecration of the site, which boosted annual attendance from 3 million to nearly 5 million by 2025. While Santín secured a spot to see the Pope in person, she chose to join him at Montserrat rather than the Sagrada Familia, following in the footsteps of her grandmother, who made a barefoot pilgrimage to the mountain during the Spanish Civil War to pray for her husband’s safety. Even as she acknowledges the Sagrada Familia’s ability to move believers and non-believers alike, she joins many local residents in expressing concern that the Pope’s visit could push tourism levels to unsustainable heights for the Barcelona community.
