Gaudí's original design calls for a total of eighteen spires, representing in ascending order of height the Twelve Apostles, the Virgin Mary, the four Evangelists and, tallest of all, Jesus Christ. Nine spires have been built as of 2021, corresponding to four apostles at the Nativity façade and four apostles at the Passion façade and the Virgin Mary spire.According to the 2005 "Works Report" of the project's official website, drawings signed by Gaudí and recently found in the Municipal Archives, indicate that the spire of the Virgin was in fact intended by Gaudí to be shorter than those of the evangelists. The spire height will follow Gaudí's intention, which according to the report will work with the existing foundation.
