Antoni Plàcid Guillem Gaudí i Corne, believed to be the greatest exponent of Catalan Modernism, was a 19th century Spanish architect. In his childhood, he spent a lot of time observing nature, discovering natural patterns, which later on helped him to develop his unique style of architecture. Starting to work soon after receiving his degree in architecture at the age of twenty-six, his first commission was to design the lampposts at Plaça Reial. Very soon, he was discovered by Catalan industrialist Eusebi Güell, who would eventually commission many of his masterpieces such as ‘Palau Guell’, ‘Park Guell’, 'Church of Colònia Güell,' etc. Concurrently, he worked on other projects as well, among which the most famous is the Basilica i Temple Expiatori de la Sagrada Familia in Barcelona. Starting to work on it at the age of thirty-one, he continued with this work until his death at the age of seventy-three. Many of his works have now been included under the UNESCO World Heritage Site list.
