In contrast to the highly decorated Nativity Façade, the Passion Façade is austere, plain and simple, with ample bare stone, and is carved with harsh straight lines to resemble a skeleton if it were reduced to only bone. Dedicated to the Passion of Christ, the suffering of Jesus during his crucifixion, the façade was intended to portray the sins of man. Construction began in 1954, following the drawings and instructions left by Gaudí for future architects and sculptors. The towers were completed in 1976, and in 1987 a team of sculptors, headed by Josep Maria Subirachs, began work sculpting the various scenes and details of the façade. They aimed to give a rigid, angular form to provoke a dramatic effect. Gaudí intended for this façade to strike fear into the onlooker. He wanted to "break" arcs and "cut" columns, and to use the effect of chiaroscuro (dark angular shadows contrasted by harsh rigid light) to further show the severity and brutality of Christ's sacrifice.
Facing the setting sun, indicative and symbolic of the death of Christ, the Passion Façade is supported by six large and inclined columns, designed to resemble sequoia trunks. Above there is a pyramidal pediment, made up of eighteen bone-shaped columns, which culminate in a large cross with a crown of thorns. Each of the four towers is dedicated to an apostle (James, Thomas, Philip, or Bartholomew) and, like the Nativity Façade, there are three porticos, each representing the theological virtues, though in a much different light.
