Mira Apartment is a famous "disharmonious block" in downtown Barcelona. There are many strange apartment buildings in this block. One of them is the Mira House. It is one of the masterpieces of Antonio Gaudi. In 1984, Mira House was selected by UNESCO for its outstanding artistic and historical value as a World Heritage Site. The building was built between 1906 and 1910, when Mr. Milla, a wealthy man, asked Gaudi to design an apartment for him and his wife. Mira's house covers an area of 1323 square meters. There are six-storey houses, one-storey attic and one underground parking lot. In 1986, the Mira House was purchased by La Caixa de Catalunya Bank. Apart from the bank office area, other public areas are available for visitors to visit. The Mira House is also nicknamed the "quarry" and its most famous symbol is the chimney shaped by soldiers wearing helmet on irregular walls and platforms. The wavy appearance of this building is composed of white stone wall, balcony railings made of twisted iron bars and slabs, and wide windows. It is very dynamic and inspires people's infinite reverie. Barcelona's greatest pride is also the masterpiece of modernist gifted architect Gaudi, who has made this peninsula pearl more dazzling. Seven pieces of a person's works have been included in the world cultural heritage, which is also a unique miracle in the world. We only visited the appearance of Mira apartment, but also encountered a lot of rain, time is limited, can only take a few photos to escape the bus, of course, a little regrettable.
