Gaudi, the magic of its creations and use of materials.
Antoni Gaudí was a Catalan architect known as the greatest exponent of Catalan Modernism.
His work was influenced by his passions in life: architecture, nature, and religion.[4] He considered every detail of his creations and integrated into his architecture such crafts as ceramics, stained glass, wrought ironwork forging and carpentry. He also introduced new techniques in the treatment of materials, such as trencadís which used waste ceramic pieces.
An early use of recycled materials on a great scale!
