Light through the windows in the Passion Façade
Gaudí said that colour was the expression of life, which is why he decided to make its presence felt in the Sagrada Familia. It is to be found on the cypress on the Nativity facade, on the pinnacles and various crowning elements of the towers and rooftops of the temple, on the episcopal attributes of fruit, ears of corn and grapes – representing the Eucharistic symbols of bread and wine – made of trencadis of Venetian glass, enamelled ceramic of several colours, brick and stone etc.Inside, apart from the colour provided by the actual construction materials used, such as the different types of stone and tiles in the vaulting, there will be many coloured symbolical features, such as the stained-glass windows and the inscriptions on the lights located in the capitals of the columns in the central nave and crossing, as well as the skylights in the vaults.
