A mix of surreal design and architectural ingenuity, Casa Milà, popularly known as La Pedrera (The Quarry), is one of the most ambitious residential Gaudi building in Barcelona.

Completed in 1912, it was declared a UNESCO World Heritage site in 1984. Situated on Passeig de Gràcia, it features a rough-hewn stone façade that undulates like a natural rock formation, with wrought-iron balconies resembling vines.

Gaudí’s innovative use of light and space is evident in the building’s interior courtyards and self-supporting stone façade, eliminating the need for load-bearing walls. The rooftop with its whimsical chimneys and ventilation towers, offers panoramic views of Barcelona.
