With this peculiarity aside, the plan, influenced by Villar's crypt, barely hints at the complexity of Gaudí's design or its deviations from traditional church architecture. There are no exact right angles to be seen inside or outside the church, and few straight lines in the design. 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. Eight spires have been built , corresponding to four apostles at the Nativity façade and four apostles at the Passion façade. 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. The Evangelists' spires will be surmounted by sculptures of their traditional symbols: a winged bull (Saint Luke), a winged man (Saint Matthew), an eagle (Saint John), and a winged lion (Saint Mark). The central spire of Jesus Christ is to be surmounted by a giant cross; its total height () will be less than that of Montjuïc hill in Barcelona, as Gaudí believed that his creation should not surpass God's. The lower spires are surmounted by communion hosts with sheaves of wheat and chalices with bunches of grapes, representing the Eucharist. Plans call for tubular bells to be placed within the spires, driven by the force of the wind, and driving sound down into the interior of the church. Gaudí performed acoustic studies to achieve the appropriate acoustic results inside the temple. However, only one bell is currently in place. The completion of the spires will make Sagrada Família the tallest church building in the world. The Church will have three grand façades: the Nativity façade to the East, the Passion façade to the West, and the Glory façade to the South (yet to be completed). The Nativity Façade was built before work was interrupted in 1935 and bears the most direct Gaudí influence. The Passion façade was built according to the design that Gaudi created in 1917. The construction began in 1954, and the steeples, built over the elliptical plan, were finished in 1976.
