<Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> The Basílica i Temple Expiatori de la Sagrada Família (Catalan pronunciation: (səˈɣɾaðə fəˈmiɫiə); Spanish: Templo Expiatorio de la Sagrada Familia; English: Basilica and Expiatory Church of the Holy Family) is a large unfinished Roman Catholic church in Barcelona, designed by Catalan architect Antoni Gaudí (1852--1926). Gaudí's work on the building is part of a UNESCO World Heritage Site, and in November 2010 Pope Benedict XVI consecrated and proclaimed it a minor basilica, as distinct from a cathedral, which must be the seat of a bishop . </P> <P> In 1882 construction of Sagrada Família commenced under architect Francisco Paula de Villar until 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 at the time of his death at age 73 in 1926, less than a quarter of the project was complete . </P> <P> Relying solely on private donations, Sagrada Familia's construction progressed slowly and was interrupted by the Spanish Civil War, only to resume intermittent progress in the 1950s . Since commencing construction in 1882, advancements in technologies such as computer aided design and computerised numerical control (CNC) have 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 could be completed by 2026--the centenary of Gaudí's death . </P>
