La Pedrera

La Pedrera, officially Casa Milà, is a residential building in Barcelona designed by architect Antoni Gaudí and completed in 1912. It is a prominent example of Catalan Modernisme and is listed as a UNESCO World Heritage site among Gaudí’s works.

The building is best known for its undulating stone facade, wrought-iron balconies, and a rooftop populated by sculptural chimneys and ventilators that form a skyline landmark. Interior highlights open to visitors include a reconstructed apartment, the attic with exhibits on Gaudí’s work, two light-filled courtyards, and the rooftop viewpoints.

Commissioned and built between 1906 and 1912, Casa Milà was developed as a private apartment block and commercial property. Its structure and parabolic arches were innovative at the time and led to both public controversy and later recognition as an architectural landmark.

It sits on Passeig de Gràcia in Barcelona’s Eixample district, a short walk from other Modernist buildings and major city attractions.

• Rooftop views: The rooftop offers panoramic views along **Passeig de Gràcia** and contains the building's most distinctive sculptural chimneys; visiting the roof is included in the standard ticket.
• UNESCO and tours: Completed in 1912, the property is part of the UNESCO listing for Antoni Gaudí's major works in Barcelona, and guided or audio tours explain the building's structural innovations.
