This monumental cathedral was always going to be Gaudi’s unfinished work, who was run over and killed by a tram in 1926. His vision of an architectural celebration of Christ’s birth, crucifixion and glorious ascension was so ambitious that here we are, and this extraordinary monument is still long way from being completed. The architects selected to carry on his work could never truly follow Gaudi’s spiritual journey, but progress is being made on what has been called the bible in stone. Gaudí designed 3 façades, representing the Nativity , the Passion and the Glory of Christ. Sagrada Familia has 8 towers, although Gaudi’s designs tells us that at the end , they will be 18: 12 representing the Apostles, 4 dedicated to the writers of the Gospels, and the final two in celebration of the Virgin Mary and Christ.
