Antoni Gaudí is a Spanish architect associated with Art Nouveau. Considered the leading exponent of Catalan modernism, Antoni Gaudí is one of the most important architects in history. His works are characterized by the incorporation of building technologies inspired by nature and by the presence of deep religious symbolism. These monuments are the expression of an eclectic and very personal style not only in architecture but also in garden art, sculpture and all forms of decorative arts. His works are classified as World Heritage by UNESCO.
