Antoni Gaudí (1852–1926) was a visionary Catalan architect and leading figure of the Spanish Art Nouveau movement. Born in Reus, Spain, he studied architecture in Barcelona, where his imaginative and nature-inspired designs flourished. Gaudí’s most iconic works include the still-unfinished Sagrada Família, Park Güell, and Casa Batlló, all celebrated for their organic forms, vibrant mosaics, and structural innovations. He pioneered techniques using ceramics, stained glass, and ironwork, creating distinctive, dreamlike spaces. Deeply religious, Gaudí devoted his later years to the Sagrada Família, which continues to define his legacy as one of history’s most creative architects.
