The life of Antoni Gaudí (1852-1926) was full of complexity and contradictions. As a young man he joined the Catalonian nationalist movement and was critical of the church; toward the end of his life he devoted himself completely to the construction of one single spectacular church, La Sagrada Familia. In his youth, he courted a glamorous social life and the demeanor of a dandy. By the time of his death in a tram accident on the streets of Barcelona his clothes were so shabby passersby assumed he was a beggar.Gaudí's incomparable architecture channels much of this multifaceted intricacy. From the shimmering textures and skeletal forms of Casa Batlló to the Hispano-Arabic matrix of Casa Vicens, his work merged the influences of Orientalism, natural forms, new materials, and religious faith into a unique Modernista aesthetic. Today, his unique aesthetic enjoys global popularity and acclaim. His magnum opus, the Sagrada Familia, is the most-visited monument in Spain, and seven of his works are UNESCO World Heritage Sites.
