Pope Leo XIV is observing the centenary of architect Antoni Gaudí’s death with ceremonies in Barcelona focused on the Sagrada Família basilica. Multiple outlets report that the pope celebrates a Mass at the basilica and marks the inauguration of the church’s final, tall spire. Coverage also describes the Sagrada Família as a major religious and cultural landmark that remains unfinished in the sense that construction has extended over many decades despite beginning a century earlier. The pope’s remarks emphasize the basilica’s character and symbolism, describing it as a “masterpiece of stones, colors and light” and framing it as a sign of unity and harmony for Spain, while also drawing a parallel between the ongoing building project and a lifelong spiritual journey. Some reports place the pope’s observance within a broader religious programme that includes a noontime prayer at a mountain-top abbey and an evening Mass at Sagrada Família. Outlets agree the ceremonies honor Gaudí’s legacy while highlighting the basilica’s continuing role as one of the world’s most visited monuments.
