Spain's little-known fantastic architecture in Barcelona

Barcelona's emerging district occupies the central plain of Barcelona and was planned in the late 19th century according to the plan of Ildefons Cerdá. The collapse of the medieval city walls that limited the development of the city made this grand urban redevelopment plan possible, connecting several towns that were then independent of Barcelona, such as the current District of Gracia. If you want to understand the scope of this urban renewal plan, just take a look at the map of the Barcelona city center. It is obvious that the giant squares of the emerging district extend from the old city to the distant residential areas - those places with narrow streets are residential areas.

Built in 1908, the Catalonia Palace of Music is one of the most exquisite concert halls in the world, also known as the "Nail House". Its colors are gorgeous, and its decorations are full of symbolic meaning, bringing a mysterious and warm characteristic to this concert hall. It is still in use today, with concerts held daily.
Casa Amatller is a colorful Dutch-style medieval building located to the left of the Batlló Apartments. The architect, Cadafalch, designed the house.
The Lion and the Mulberry Tree House is a building designed by the famous modernist architect Luis Domènech i Montaner. It is located at 35 Gràcia Avenue in Barcelona's Eixample district, at the intersection of One Hundred Street, and is one of the three important buildings in the city's discordant neighborhood. It was first built in 1864 and renovated in 1902. Unlike many buildings at the time, it was not named after the owner, but after the lions and mulberry trees depicted in its decorative pattern.
The Hospital de Sant Pau, a masterpiece of the architect Montaner father and son, was included in the UNESCO World Heritage List in 1997. The hospital is composed of colorful mosaic decorated buildings, with 48 underground interconnected wards. Gardens and green spots are dotted around the buildings, providing an elegant environment for the patients. The top of the entrance tower offers a view of the entire hospital. Decorated with mosaic puzzles and sculptures by Pablo Gargallo, the buildings and courtyards are adorned with Islamic art style ceilings and stairs. The hospital was in use as a medical institution until 2009. Today, this grand building has been converted into an art school (Escola Massana) and the Catalonia Library (Biblioteca de Catalunya). Upon entering these places, you can still feel the historical atmosphere of the hospital era.
The Antoni Tàpies Foundation (Fundació Antoni Tàpies) was founded by the artist Antoni Tàpies in 1984 with the aim of promoting the development of contemporary art culture. The museum mainly exhibits works by Antoni himself and other contemporary artists, with the most representative being a huge sock called "The Sock", measuring 2.75 meters, which has caused great controversy.
Casa Comalat is located on Avenida Diagonal in Barcelona and showcases modernist architecture, paying tribute to Antoni Gaudi. It was built between 1909 and 1911 by architect Salvador Valeri i Pupurull, who was greatly influenced by Gaudi's organic architectural style. The building's unique roof resembles a clown's hat.
