Pope Leo blessed the Sagrada Família in Barcelona on June 10, 2026, to mark the completion of the church's central spire [1].

The event signifies the end of structural work on the central tower and establishes the basilica as the tallest church in the world [2]. This milestone coincides with the 100th anniversary of the death of its visionary architect, Antoni Gaudí [3].

During the visit, the pontiff delivered Mass to a crowd of 8,000 people [4]. The ceremony celebrated the conclusion of a construction process that has spanned 144 years [5]. The central spire reached completion earlier this year in February 2026 [6].

The Sagrada Família has remained under construction since the late 19th century, evolving through generations of architects to realize Gaudí's complex organic designs. The completion of the spire represents the final major structural hurdle for the basilica, a project that has become a global symbol of Barcelona and Catalan identity.

While some reports described the basilica as nearly complete, others noted the specific completion of the tower [7]. The papal visit served as both a religious consecration and a tribute to the architectural legacy of Gaudí, who died in 1926 [3].

The Sagrada Família is now the world’s tallest church.

The completion of the central spire and the subsequent papal blessing transition the Sagrada Família from a perpetual construction site to a finished architectural monument. By timing the event with the centenary of Gaudí's death, the Catholic Church and the city of Barcelona have linked the building's structural success to its spiritual and historical origins, cementing the site's status as a primary global pilgrimage and tourism destination.
