The Basílica de la Sagrada Família, is a large unfinished Roman Catholic minor basilica in Barcelona. Designed by Spanish/Catalan architect Antoni Gaudí (1852–1926), his work on the building is part of a UNESCO World Heritage Site. On 19 March 1882, construction of the Sagrada Família began under architect Francisco de Paula del Villar. In 1883, when Villar resigned, Gaudí took over as chief architect, transforming the project with his architectural and engineering style, combining Gothic and curvilinear Art Nouveau forms. Gaudí devoted the remainder of his life to the project, and he is buried in the crypt. At the time of his death in 1926, less than a quarter of the project was complete. In July 1936, revolutionaries set fire to the crypt and broke their way into the workshop, partially destroying Gaudí's original plans, drawings and plaster models, which led to 16 years work to piece together the fragments of the master model. Construction resumed to intermittent progress in the 1950s. Advancements in technologies such as computer aided design and computerised numerical control (CNC) have since enabled faster progress and construction passed the midpoint in 2010. However, some of the project's greatest challenges remain, including the construction of ten more spires, each symbolising an important Biblical figure in the New Testament. It is anticipated that the building can be completed by 2026, the centenary of Gaudí's death. (wikipedia)
