Casa Mila in Barcelona is an early twentieth-century apartment building by Antoni Gaudí, recognised for its undulating stone facade and sculptural rooftop terrace. Completed in the early 1910s, it stands on Passeig de Gràcia as one of Gaudí’s major residential works and later became part of a UNESCO World Heritage listing of his architecture.
An apartment block turned architectural landmark
Casa Mila was commissioned by the industrialist Pere Milà i Camps and his wife Roser Segimon, who acquired the corner plot on Passeig de Gràcia in 1905 and engaged Gaudí to design their new residence and income-generating apartments.Pere Milà and his wife Construction began in 1906 and the building was structurally complete a few years later, with finishing work continuing into the early 1910s.built between 1906 and 1912
From the street, the building reads as a continuous Modernista stone volume rather than a conventional front of separate dwellings.Modernista building Behind this, Gaudí arranged apartments around internal courtyards, bringing daylight into the depth of the block and distinguishing Casa Mila from more traditional Eixample constructions with single street-facing facades and darker interiors. The building still contains private apartments alongside spaces that are accessible as exhibition and interpretation areas.
Stone waves, ironwork and courtyards
Casa Mila occupies a corner site at number 92 Passeig de Gràcia, meeting Carrer de Provença, and its exterior follows the two streets in a continuous curve.Passeig de Gràcia 92 The facade is built from pale limestone blocks, cut and laid to produce a rippling surface that suggested a stone quarry to early observers and led to the building’s popular name La Pedrera. Wrought-iron balconies fold out from this surface in varied patterns, forming a second layer of texture against the stone.
Within, two main courtyards create vertical voids that extend from the ground level up to the roof, separating apartment sections and providing air and light.courtyards inside the block Gaudí used parabolic arches in the attic structure and varied support systems to reduce the need for load-bearing interior walls, allowing apartment layouts that were more flexible than most domestic buildings of the time. Decorative schemes inside the main staircase halls and principal floors pick up organic and geometric motifs seen in other Gaudí works around Barcelona.
The rooftop terrace and World Heritage status
The roof terrace of Casa Mila is one of its most distinctive features, treated not as a purely functional surface but as a sculptural landscape above the city.sculptural chimneys on the roof Chimneys and ventilation towers rise from the deck as freestanding figures, some clad in broken ceramic or stone fragments, and arranged so that the skyline becomes part of the architectural composition. Visitors can walk between these elements and look down into the courtyards and across the Eixample grid.
Casa Mila was declared a Monument of National Historical and Artistic Interest by the Spanish government in 1969 and later included in international heritage listings.national monument status In 1984, it was inscribed by UNESCO as part of “Works of Antoni Gaudí”, recognising its outstanding universal value alongside Park Güell and Palau Güell.UNESCO inscription in 1984 The listing confirms Casa Mila’s role in the development of Barcelona’s architecture and secures protection for both its exterior and key interior spaces.
