City Walk in Barcelona.

City Walk is a great way to explore the architectural beauty of Barcelona. Barcelona is a stronghold of the Art Nouveau movement, so you'll often come across buildings that reflect this style or are influenced by it. The Art Nouveau movement began in the late 19th century and lasted until the early 20th century. It was an important art and design movement in Europe and North America. The name comes from a gallery called "Maison de l'Art Nouveau" that Samuel Bing opened in Paris in 1895. The gallery displayed products designed in his new style. The Art Nouveau movement was not just an art style, but a wide-ranging movement that covered architecture, furniture, clothing, product design, and more. Its main characteristics are: curvilinear style, with the Art Nouveau movement emphasizing the use of curved, natural lines and rejecting traditional straight lines; organic forms, pursuing organic shapes and symbolism, and drawing design inspiration from nature; decorative art, focusing on decoration, using rich colors and delicate patterns; symbolism, with symbolism replacing traditional narrative and becoming an important element in design.
