Art Nouveau is an artistic movement that emerged in the late 19th century, characterized by its organic forms and intricate designs. It sought to break away from traditional styles, emphasizing flowing lines, natural shapes, and decorative elements inspired by nature, such as flowers and plants. This movement influenced various art forms, including architecture, graphic design, and furniture. Notable figures associated with Art Nouveau include Alphonse Mucha, known for his posters, and Antoni Gaudí, famous for his unique architectural works in Barcelona. The style remains celebrated for its elegance and creativity.
