On Paseo Deglas Cia Avenue in Barcelona, there is a world-famous building with pure modern style-Mira apartment. People often call it a "stone house". Together with two other works by Gaudi, it was declared as a world cultural heritage by UNESCO in 1984. Pere Milla is a rich man. After visiting bartholomew's apartment, he and his wife were very envious and decided to build a more amazing building. Milla found a very popular young architect Gaudi, asked him to design and build, and promised him full freedom of creation and action. Only later did he realize that his promise was thoughtless. The project is in full swing. Milla, on the other hand, lingered anxiously on the construction site, because there were many puzzling questions in his mind: Why did the project start without drawings? Why is there no budget? Why is there no design scheme? And so on. Gaudi is silent-language is not the only and best way for him to express his views. However, one day, he lost his temper, took out a crumpled piece of paper from his pocket and said to Milla, "This is my apartment design!" " Poor Milla sometimes grabbed his wallet and sometimes grabbed his chest, but Gaudi smiled casually. He rubbed his hands proudly and said to Milla, "The strange shape of this house will echo the various mountains around Barcelona." Mira apartment has a patchwork roof, uneven walls and winding curves everywhere. The whole building is like a rough sea, full of movement. Gaudi also built some grotesque protrusions on the roof of Mira apartment, some like armed soldiers, some like mythical monsters, and some like church bells. In fact, this is a special form of chimney and ventilation duct. Later, like Gouel Park and Sagrada Familia Cathedral, it became a symbol of Barcelona. In a word, Mira apartment looks strange inside and outside, even absurd. But Gaudi thinks this is the best house he has ever built, because he thinks it is "the most convincing work to embody romanticism and anti-traditional spirit in architecture with naturalism".
