The Sagrada Família is Antoni Gaudí’s most famous work and one of the most unique temples in the world. Its construction began in 1882 as a civic initiative promoted by the bookseller Josep Maria Bocabella, who envisioned a great expiatory temple in an industrial and rapidly changing Barcelona. Gaudí took over in 1883, replacing the original neo-Gothic design with a monumental vision that integrated faith, nature, and technique. For 43 years —and especially during the last fourteen of his life— he worked almost exclusively on the project: columns like tree trunks branching out, vaults inspired by forest canopies, and light that evokes a woodland atmosphere. During his lifetime, he focused mainly on the Nativity Façade, conceived as both a statement of intent and a visual appeal to attract donations. As an expiatory temple, the Sagrada Família has always been funded through private contributions, including income from visitors. After Gaudí’s death in 1926, the work continued thanks to the models and geometric calculations he left behind. The Civil War destroyed part of the workshop, but construction resumed in the mid-20th century. Today, with the central towers nearing completion, the building continues to rise —faithful to Gaudí’s method while adapting to the challenges of the 21st century.
