Sagrada Família, is a large Roman Catholic church in Barcelona, Catalonia, Spain, designed by Catalan architect Antoni Gaudí (1852–1926). Although incomplete, the church is a UNESCO World Heritage Site,and in November 2010 was consecrated and proclaimed a minor basilica by Pope Benedict XVI.
Though construction of Sagrada Família had commenced in 1882, Gaudí became involved in 1883, taking over the project and transforming it with his architectural and engineering style—combining Gothic and curvilinear Art Nouveau forms.
Gaudí devoted his last years to the project and at the time of his death in 1926, less than a quarter of the project was complete.
Sagrada Família's construction progressed slowly as it relied on private donations and was interrupted by the Spanish Civil War—only to resume intermittent progress in the 1950s. Construction passed the mid-point in 2010 with some of the project's greatest challenges remaining and an anticipated completion date of 2026—the centennial of Gaudí's death. The basílica has a long history of dividing the citizens of Barcelona—over the initial possibility it might compete with Barcelona's cathedral, over Gaudí's design itself, over the possibility that work after Gaudí's death disregarded his design, and the recent possibility that an underground tunnel of Spain's high-speed train could disturb its stability.
Gaudí's original design calls for a total of eighteen spires, representing in ascending order of height the Twelve Apostles, the four Evangelists, the Virgin Mary and, tallest of all, Jesus Christ. Eight spires have been built as of 2010, corresponding to four apostles at the Nativity façade and four apostles at the Passion façade.
The completion of the spires will make Sagrada Família the tallest church building in the world.
The columns of the interior are a unique Gaudí design. Besides branching to support their load, their ever-changing surfaces are the result of the intersection of various geometric forms. The simplest example is that of a square base evolving into an octagon as the column rises, then a sixteen-sided form, and eventually to a circle. This effect is the result of a three-dimensional intersection of helicoidal columns (for example a square cross-section column twisting clockwise and a similar one twisting counter-clockwise).
Essentially none of the interior surfaces are flat; the ornamentation is comprehensive and rich, consisting in large part of abstract shapes which combine smooth curves and jagged points. Even detail-level work such as the iron railings for balconies and stairways are full of curvaceous elaboration.
On the subject of the extremely long construction period, Gaudí is said to have remarked, "My client is not in a hurry."
