French broadcaster ARTE has released a documentary detailing the life of Antoni Gaudí and the construction of the Sagrada Família basilica [1].

The film arrives as the landmark approaches a major milestone with the scheduled inauguration of its highest tower on June 10 [1]. This event represents a significant step toward completing a structure that has remained unfinished for over a century.

The documentary focuses on the artistic and technical challenges involved in realizing the vision of Antoni Gaudí, who lived from 1852 to 1926 [1]. By examining the intersection of Gaudí's unique architectural style and the modern engineering required to finish the work, the production provides a portrait of the man and his enduring influence on Barcelona.

Construction of the Sagrada Família began in 1882 [1]. The project has spanned multiple generations of architects and builders, evolving from a 19th-century design into a global symbol of Catalan Modernism. The current phase of work emphasizes the completion of the central towers, which serve as the focal point of the basilica's skyline.

ARTE has made the documentary available for viewing until Dec. 29, 2026 [1]. The film serves as both a celebration of the upcoming tower opening and a historical record of the basilica's slow progress toward completion.

Because the project has outlived its creator by nearly a century, the documentary highlights the tension between original intent and modern execution. The highest tower is the most critical element of this final push, as it defines the overall silhouette of the church against the city of Barcelona.

The documentary is available until Dec. 29, 2026.

The inauguration of the highest tower signifies the nearing completion of one of the world's most famous long-term construction projects. By pairing the event with a documentary on Gaudí, the project organizers are framing the technical achievement as a fulfillment of a century-old artistic dream, bridging the gap between 19th-century craftsmanship and 21st-century engineering.
