The church has 12 towers, representing the Twelve Apostles. The western facade is known as the Passion Facade, the eastern one is the Nativity Facade, and the southern is the Glory Facade. Each features an entirely different portal. The Nativity Facade was completed according to Gaudi's original plans before 1935 celebrates the birth of Christ. The cypress tree already foreshadows the fate of the newborn Christ. At the foot of the tree there is a pelican and a group of angels holding chalices, the symbols of the Eucharist and the sacrifice. The top of the tree bears a red Tau cross marked with an X, referring to Christ, and a dove, symbol of the Holy Spirit. The base columns contain sculptures of turtles, a Chinese symbol of order within chaos and the stability of the cosmos. The Passion Facade, still under construction, commemorates the suffering and the death of Christ. The impressive angular sculptures were produced byJosep Maria Subirach. A crypt under the church holds the grave of its original creator, Antoni Gaudi is buried.
