1. Antoni Gaudí
Gaudí spent his entire career in Barcelona, where he built all of his projects, the most famous of which is the 1883 cathedral known as La Sagrada Familia, still under construction today. His style was an ornate mix of Baroque, Gothic, Moorish and Victorian elements that often featured ornamental tile-work, and drew upon forms found in nature—an influence that can he seen in the tree-like columns holding up the vast interior of his church, as well as the undulating facade of another of his famous creations, the apartment block known as the Casa Milla (inspired by the multi-peaked mountain just outside of Barcelona called Montserrat). Gaudí’s work would go on to have a tremendous impact on subsequent generations of modernists.
