Constructed between 1894 and 1930, the Nativity façade was the first façade to be completed. Dedicated to the birth of Jesus, it is decorated with scenes reminiscent of elements of life. Characteristic of Gaudí's naturalistic style, the sculptures are ornately arranged and decorated with scenes and images from nature, each a symbol in its own manner. For instance, the three porticos are separated by two large columns, and at the base of each lies a turtle or a tortoise (one to represent the land and the other the sea; each are symbols of time as something set in stone and unchangeable). In contrast to the figures of turtles and their symbolism, two chameleons can be found at either side of the façade, and are symbolic of change.
