Casa Batlló
Casa Batlló is a celebrated Modernisme building at 43 Passeig de Gràcia in the Eixample district of Barcelona, Spain. Redesigned between 1904 and 1906 by Antoni Gaudí for textile industrialist Josep Batlló i Casanovas, it is widely regarded as one of the master’s most inventive works — a remodelling of an existing 1877 structure transformed into a rippling façade of coloured ceramics, bone-like columns and a dragon-scaled roof. The building was declared a UNESCO World Heritage Site in 2005 as part of the collective inscription of Gaudí’s works.

Overview
Casa Batlló stands on the celebrated “Block of Discord” on Passeig de Gràcia, alongside buildings by Lluís Domènech i Montaner and Josep Puig i Cadafalch. Gaudí’s assistants Domènec Sugrañes i Gras, Josep Canaleta and Joan Rubió contributed to the renovation project alongside the master. The building is today managed as a cultural site open to the public, regularly attracting over one million visitors per year.
History
The original building on the site was constructed in 1877 by architect Emilio Sala Cortés. Josep Batlló i Casanovas, a wealthy textile manufacturer, purchased it in 1900 and commissioned Antoni Gaudí to carry out a thorough remodelling rather than a complete demolition. Work proceeded between 1904 and 1906, transforming an unremarkable residential block into one of Barcelona’s most distinctive landmarks. Gaudí retained the structural skeleton but redesigned every surface, interior and façade, introducing his characteristic biomorphic language throughout.
What you see
The façade is clad in a mosaic of broken ceramic tiles (trencadís) in shades of blue, green and violet that shift colour as light changes through the day. Columns on the ground floor resemble bones or femurs, giving rise to a popular nickname — Casa dels Ossos, the House of Bones. The roof, covered with arching ceramic scales, evokes the spine and back of a dragon, and is crowned by a cross of four arms set on a pinnacle tower. Inside, the central light well is tiled in gradated blues from dark at the base to pale at the top, ensuring even illumination on every floor.
Cultural significance
Casa Batlló was inscribed on the UNESCO World Heritage List in 2005 as part of the group inscription “Works of Antoni Gaudí,” recognising it as an outstanding example of the creative genius of Catalan Modernisme. It is considered a defining statement of organic, nature-inspired architecture and continues to influence contemporary design globally. The building remains in private ownership by the Batlló family foundation, which has led its preservation and public-access programme.
