Construction began in 1882 under architect Francisco de Paula del Villar, but Antoni Gaudí assumed control a year later and transformed the project into a synthesis of Gothic revival and Art Nouveau organicism. His death in 1926 left the basilica one-quarter complete.
Today, nine generations of architects have continued his vision using plaster models, drawings, and computational stone-cutting techniques he never imagined. The Nativity Facade, finished during Gaudí's lifetime, remains the most faithful to his hand. Its sculpted nativity scenes rise in vertical cascades of stone flora and fauna, each column shaped to resemble tree trunks that branch into the vaulted ceiling above.
Pope Benedict XVI consecrated the basilica as a minor basilica in 2010, marking its transition from construction site to functioning place of worship. The interior's forest of columns filters Mediterranean light through stained glass designed to shift in color with the sun's position—blue and green hues dominate the eastern apse at dawn, amber and red ignite the western nave by late afternoon. The columns themselves lean at calculated angles, their branching capitals distributing weight the way organic structures do, eliminating the need for flying buttresses. Priority access to the Passion Facade tower reveals Barcelona's grid sprawling toward Montjuïc, the Mediterranean a stripe of cobalt beyond the rooftops. The 340-step spiral ascent is narrow and one-way; claustrophobia should be considered before booking tower options.
Gaudí envisioned eighteen spires representing the Twelve Apostles, the Virgin Mary, the four Evangelists, and Jesus Christ—the central tower will rise to 172.5 meters when completed, making it the tallest church structure built entirely by human hands. Completion estimates hover near 2026, the centennial of Gaudí's death, though construction depends on private donations and ticket revenue. Sagrada familia skip the line with tower access tours allow focused time inside the basilica without the multi-hour queues that form daily by mid-morning. Audio guides narrate the symbolism encoded in every facade, from the Passion's stark geometry representing Christ's suffering to the Glory Facade's apocalyptic imagery still under construction. The crypt beneath holds Gaudí's tomb, a plain stone marker in contrast to the exuberance overhead.
