Antoni Gaud was a Catalan architect of Spanish. Gauds works reflect his highly individual and distinctive style and are largely concentrated in the Catalan capital of Barcelona, notably his magnum opus, the Sagrada Famlia.Much of Gauds work was marked by his big passions in life: architecture, nature, religion. Gaud studied every detail of his creations, integrating into his architecture a series of crafts in which he was skilled: ceramics, stained glass, wrought ironwork forging and carpentry. He introduced new techniques in the treatment of materials.The Casa Mila apartment house was a late example of Antonio Gaudi s apartment house. On a corner site, the building facade is curvilinear in form and based on organic concepts. The heavy facade is tied to the floors behind. The most successful portions of the design were the roof vaults, clustered chimneys, and balcony railings. This design caused much public comment, and Antonio Gaudi was forced to defend his organic forms in general terms.A new church, the Sagrada Familia Church in Barcelona, was to be dedicated to the holy family. In 1883, Antonio Gaudi was recommended to replace the original architect who had resigned. At age 31, Antonio Gaudi undertook what became his lifes work. During the years that Antonio Gaudi was working on the crypt, he was formulating design ideas to be expressed in the church above. The east transept was selected for a presentation of the Nativity, and work began on the apse, the lower part of the towers, and the entrance doors. Now please let my partner lanmeng to continue this speech.By 1901, work began on the upper part of the towers, and there the shift from a more traditional beginning to a new style can be seen. The square base of the towers was modified into the round towers, which grew ever freer in design as the work progressed. After 1910, Antonio Gaudi spent all of his effort on religious commision, and the east front towers were completed after his death in 1926. Work continued until 1935, when it was stopped by the Spanish Civil War. Antonio Gaudi left a number of models for the completion of the nave and the two other main facades. His plans included a central tower higher than St. Peters in Rome. After a few years, under the influence of neo-Gothic art and Oriental techniques, Gaud became part of the Modernista movement which was reaching its peak in the late 19th and early 20th centuries. His work transcended mainstream Modernisme, culminating in an organic style inspired by nature. Gaud rarely drew detailed plans of his works, instead preferring to create them as three-dimensional scale models and molding the details as he was conceiving them.Gauds work enjoys widespread international appeal and many studies are devoted to understanding his architecture. Today, his work finds admirers among architects and the general public alike. His masterpiece, the still-uncompleted Sagrada Famlia, is one of the most visited monuments in Catalonia.4 Between 1984 and 2005, seven of his works were declared World Heritage Sites by UNESCO.
