Casa Milà, a major civil work by Antoni Gaudí built between 1906 and 1912 in Barcelona, arouses perplexity and controversy. Renamed "La Pedrera" (quarry) by the people of Barcelona, this audacious building breaks with the architectural conventions of the time.

Inspired by nature and anatomy, Gaudí designed an innovative structure: an undulating façade, load-bearing columns, and luminous patios at the heart of the building.

Despite his visionary genius, his eccentric choices and budget overruns cause tensions with the patrons, the Milàs.

Today, this sculptural and functional work embodies both modernism and universal heritage.
