Antoni Gaudi was a Spanish Catalan architect who lived from 1852 to 1826 and was the master of Catalan modernism. Most of Gaudi's work was characterized by his 3 passions in life; religion, nature and architecture. His works show various unique styles that he achieved through researching natural forms and employing them in his buildings while studying every detail of his creations, assimilating every innovative design solution into his design. He was influenced by Gothic Revival art and became a major part of the Modernism movement, although his works transcended traditional Modernism design. He used organic styles inspired by shapes he found in nature and rarely drew designs, preferring instead to use patterns and 3D molding. His works are largely concentrated in Barcelona, ​​7 of which have been designated a World Heritage Site by UNESCO, especially his great yet incomplete masterpiece, the Sagrada Familia. Antoni Gaudi was born in Riudoms or Reus in 1852. He was the youngest of 5 children and one of 3 to survive to adulthood. His exact place of birth is a mystery because no supporting documents have been found, causing controversy as to whether he was born in Reus or Riudoms. He had a great appreciation for his homeland and pride in his heritage, thinking that Mediterranean peoples were creative and had a subconscious sense for design. As a child Gaudi suffered from rheumatism and poor general health which probably contributed to his reserved nature. These health problems and the theories of hygienist Dr. Kneipp facilitated Gaudi's transition to vegetarianism. His religion and vegetarianism led him to undertake several long fasts which were often unhealthy and which led to a fatal illness in 1894. the vaults have a center and allow holes to let in natural light. He complemented his organic vision of architecture with a unique spatial vision that would allow him to conceive projects in three dimensions. With this special conception he always preferred to use casts and scale models, being reluctant to make plans and only very rarely sketching his work. In the history of architecture Gaudi has the position of a creative genius who, inspired by the forms he found in nature, developed his own architectural style and achieved aesthetic value as well as technical perfection. His structural innovations were largely the result of his journey through many styles and genres of design, Baroque, Gothic and traditional Catalan, often saying the styles culminated in his work, reinterpreting and improving them..
