An excerpt from the article 22 facts about La Sagrada Familia
Thirty-one-year-old Gaudi presented a completely new design of the building. It assumed building a church without external arches and buttresses, with an enlarged central tower 172.5 meters high. The church was to be devoted to Jesus Christ. As mystical-religious references were of great importance in Gaudi's work, he prepared a complex iconographic program.
