Antoni Gaudí''s life was marked by complexity and contradictions. He started as a critic of the church and supporter of Catalonian nationalism, but later devoted himself to building La Sagrada Familia. His architecture, such as Casa Batlló and Casa Vicens, blends Orientalism, natural forms, and religious faith. Gaudí''s unique Modernista style is globally acclaimed, with seven of his works designated as UNESCO World Heritage Sites. The Sagrada Familia, his masterpiece, is Spain''s most-visited monument.
