Sagrada Familia Becomes World's Tallest Church Following Completion of Jesus Tower

OPA WIRE, Nov 1 (OPA) — A century after the death of architect Antoni Gaudí, the Sagrada Familia has reached its most significant structural milestone. The completion of the 172.5-meter central Jesus Tower cements the basilica's status as the tallest church globally. Gaudí, who died in 1926 after being struck by a tram, left behind a complex legacy that his successors struggled to interpret after many of his original models were destroyed during the 1936 Spanish Civil War.

Gaudí’s architectural vision relied heavily on the catenary arch, a structural form he studied through the ancient Taq Kasra in modern-day Iraq. By utilizing this geometry, Gaudí eliminated the need for traditional Gothic flying buttresses, which he viewed as structural crutches. Liam Duff, a structural engineer at Arup, noted that Gaudí redesigned the temple three times, eventually incorporating tree-like branching columns to support the immense weight of the nave and towers.

Modern engineering challenges required innovative solutions to maintain the architect's original aesthetic while ensuring structural integrity. When constructing the 138-meter Virgin Mary Tower, engineers faced weight constraints that threatened the stability of the foundation. In 2014, the project team collaborated with the British firm Arup to replace heavy traditional masonry with a system of tensioned stone panels reinforced by internal steel cables, significantly reducing the overall load.

Despite the technical hurdles, the project remains a testament to Gaudí’s synthesis of mathematics and faith. The interior, characterized by light filtering through stained glass onto organic, branching pillars, continues to draw millions of visitors. As work progresses toward the final completion of the basilica, the integration of ancient structural principles with modern engineering ensures that the monument remains a functional, self-supporting marvel of contemporary architecture.
