Casa Mila History Explained

Gaudi Begins the Project

Gaudi Begins the Project

1905 - 1906

Casa Mila’s story begins in June 1905. Passeig de Gràcia became a popular avenue in Barcelona, prompting the newly-married Rosario Segimón i Artells and Pere Milà i Camps to buy a house measuring 1,835 square metres at number 92 2. Hoping to create a house worthy of their name, the couple commissioned architect Antoni Gaudi to construct the building. Gaudi took less than a year to lay out his designs, with the project approved by the Barcelona City Council in February 1906.

Roadblocks

1907 - 1910

Barcelona City Council, who had approved the building’s construction, complained that Casa Mila's facade occupied part of the pavement on Passeig de Gràcia in December 1907. Rosario Segimón i Artells and Pere Milà i Camps were asked to pay a fine of 100,000 pesetas or demolish the attic and the rooftop a year later. The couple kept at it and received the permit thanks to the Eixample Commission, who certified the building was a monument in nature.

Open to Move

1911 - 1929

The speed of work on Casa Mila was ramped up, with the Barcelona City Council granting occupancy permission for the main floor after Gaudi certified the construction of the main floor was completed. The Spanish architect signed another certificate in October 1912, declaring the construction was over and occupants could move in.

Casa Mila

Civil War

1936 - 1953

The Spanish Civil War impacted Casa Mila, with the United Socialist Party of Catalonia (PSUC) seizing the building in 1936. It housed the Catalan Ministry of the Economy and Agriculture during the War, and Minister Joan Comorera occupied the main floor as his private home. Following the War, Rosario Segimón, widowed by now, sold Casa Mila to the Immobiliària Provença real estate company.

Construction of Casa Mila

Casa Mila is a masterpiece by Spanish architect Antoni Gaudí. It marked the beginning of a groundbreaking architectural movement as Gaudí embraced organic forms and seamless integration with nature. The building is among Gaudi’s most renowned works, alongside other iconic attractions in Barcelona like the Sagrada Familia and Casa Batlló.

Casa Mila, a UNESCO World Heritage Site, revolutionized architectural thinking, elevating Gaudí's popularity globally. Its notable undulating façade, adorned with limestone mosaics, grants the building an organic and distinctive allure, earning it the moniker "La Pedrera" or "The Quarry." The interior showcases Gaudí's commitment to abundant natural light and ventilation, achieved through well-placed skylights and inviting courtyards.
