Antoni Gaudí i Cornet was a Catalan architect known as the greatest exponent of Catalan Modernism. Most of his works are located in Barcelona, including his main work, the church of the Sagrada Família. Gaudí's work was influenced by his passions in life: architecture, nature, and religion. 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.
