Pope Leo XIV blessed the newly completed Tower of Jesus Christ in Barcelona on Wednesday, marking the official completion of the Sagrada Família [1].

The event signifies the end of a construction process that spanned generations, establishing the basilica as the tallest church in the world [2]. The completion arrives exactly 100 years after the death of the cathedral's architect, Antoni Gaudí [3].

Fireworks and a coordinated light show illuminated the structure following the papal blessing [1]. The celebration drew a crowd of approximately 120,000 people [4]. The Tower of Jesus Christ serves as the final piece of the architectural puzzle, fulfilling the design vision for the basilica [2].

The ceremony focused on the spiritual and architectural significance of the site. The Pope's visit to Spain coincided with the inauguration of the final tower, which now stands as the highest point of the church [2]. The event was broadcast globally, with footage of the celebrations released on Thursday [1].

Officials organized the festivities to honor the legacy of Gaudí and the persistence of the builders who worked on the site for a century. The scale of the gathering underscores the global interest in the project, a landmark that has remained under construction since 1882 [3].

Because the project relied on private donations and visitor fees, the completion of the Tower of Jesus Christ represents a financial and engineering milestone for the city of Barcelona [2]. The event concludes one of the longest-running construction projects in modern history [3].

The basilica becomes the world's tallest church.

The completion of the Sagrada Família marks the transition of the site from a perpetual construction zone to a finished monument. By achieving the status of the world's tallest church, the basilica solidifies Barcelona's position as a global center for architectural tourism and religious pilgrimage, while closing a century-long chapter of urban development initiated by Antoni Gaudí.
