In stark contrast to the miminal, hard and bare Passion Façade, the Nativity Façade is decorated and highly ornate. The façade faces the rising sun to the northeast, a symbol for the birth of Christ.
Originally, Gaudí intended for this façade to be polychromed, for each archivolt to be painted with a wide array of colours. He wanted every statue and figure to be painted. In this way the figures of humans would appear as much alive as the figures of plants and animals.
Gaudí chose this façade to embody the structure and decoration of the whole church. He was well aware that he would not finish the church and that he would need to set an artistic and architectural example for others to follow. He also chose for this façade to be the first on which to begin construction and for it to be, in his opinion, the most attractive and accessible to the public. He believed that if he had begun construction with the Passion Façade, people would have withdrawn at the sight of it.
