Sagrada Familia Barcelona
Sagrada Família Barcelona, Spain - situation 2017
Construction of the Temple Expiatori de la Sagrada Família began in 1882. The temple is still under construction, with completion expected in 2026. It is perhaps the best known structure of Catalan Modernism, drawing over three million visitors annually. Architect Antoni Gaudi worked on the project until his death in 1926, in full anticipation he would not live to see it finished.
Gaudi was appointed architect in 1883 at 31 years of age, following disagreements between the temple’s promoters and the original architect, del Villar. He maintained del Villar’s Latin cross plan, typical of Gothic cathedrals, but departed from the Gothic in several significant ways. Most notably, Gaudi developed a system of angled columns and hyperbolical vaults to eliminate the need for flying buttresses. Rather than relying on exterior elements, horizontal loads are transferred through columns on the interior. La Sagrada Familia utilizes three-dimensional forms comprised of ruled surfaces, including hyperboloids, parabolas, helicoids, and conoids. These complex shapes allow for a thinner, finer structure, and are intended to enhance the temple’s acoustics and quality of light. Gaudi used plaster models to develop the design, including a 1:10 scale model of the main nave measuring five meters in height and width by two meters in depth. He also devised a system of strings and weights suspended from a plan of the temple on the ceiling. From this inverted model he derived the necessary angles of the columns, vaults, and arches. This is evident in the slanted columns of the Passion facade, which recall tensile structures but act in compression.
Gaudi embedded religious symbolism in each aspect of La Sagrada Familia, creating a visual representation of Christian beliefs. He designed three iconic facades for the basilica, the Glory, Nativity, and Passion facades, facing south, east, and west, respectively. The sculpting of the Nativity facade recalls smooth, intricate corbelling and was overseen by Gaudi. The central nave soars to a height of 45 meters, and is designed to resemble a forest of multi-hued piers in Montjuïc and granite. The piers change in cross section from base to terminus, increasing in number of vertices from polygonal to circular. The slender, bifurcating columns draw the eye upward, where light filters through circular apertures in the vaults. These are finished in Venetian glass tiles of green and gold, articulating the lines of the hyperboloids.
Once completed, La Sagrada Familia will feature eighteen towers. Four bell towers representing the Apostles crown each facade, reaching approximately 100 meters in height. At the north end, a tower representing the Virgin Mary will stand over the apse. The central tower will reach 72 meters in height and symbolize Christ, surrounded by four towers representing the Evangelists. Subsequent generations of craftsman and architects have relied on the remaining drawings and plaster models to advance the project, adhering to Gaudi’s vision as closely as possible. As a result, the design of the temple is a collaboration spanning centuries. Gaudi himself viewed the project as the collective work of generations. "I will grow old but others will come after me. What must always be conserved is the spirit of the work, but its life has to depend on the generations it is handed down to and with whom it lives and is incarnated." Area: 4.500 m2
