Toggle🌆 Overview
On the elegant boulevard of Passeig de Gràcia, two of Antoni Gaudí’s most celebrated creations — Casa Batlló and Casa Milà (La Pedrera) — stand as living expressions of imagination turned to stone. For a full travel guide covering all major attractions, transport, and accommodation in the city, see our Ultimate Barcelona Guide. This famed street connects the lively La Rambla – The Heart of the City with the upscale area of Gràcia. Both buildings redefined architectural norms at the dawn of the 20th century and remain enduring icons of Catalan Modernisme and Barcelona’s identity.
🧱 The Artistic Vision of Antoni Gaudí
Gaudí’s philosophy was rooted in nature, symbolism, and fluidity. Every curve, mosaic, and iron detail in these houses carries meaning — not just decoration. Through them, Gaudí demonstrated that architecture could be both functional and poetic, structural yet dreamlike.
🌀 Casa Batlló – The House of Bones
🎨 A Symphony of Color and Form
Casa Batlló (1904–1906) is a masterpiece of color, symbolism, and organic design. The façade ripples like ocean waves, covered in mosaics of broken ceramic tiles — trencadís, Gaudí’s signature style. Its balconies resemble skulls, while the columns look like bones, earning it the nickname “The House of Bones.”
🐉 The Dragon and Saint George
At the rooftop, Gaudí subtly tells the story of Saint George and the Dragon, a beloved Catalan legend. The roof’s scaled tiles form the dragon’s back, and the cross-shaped turret represents Saint George’s sword piercing the beast.
🕯️ Inside the Dream
Visitors find a flowing interior with no straight lines, where light, ventilation, and beauty coexist. The noble floor — once the Batlló family home — showcases delicate stained glass, woodwork, and marine-inspired details that evoke the sea and sky.
💬 Visitor Experience
Today, Casa Batlló offers immersive tours with augmented reality, allowing guests to experience Gaudí’s world as he envisioned it — dynamic, symbolic, and timeless.

🏛️ Casa Milà (La Pedrera) – The Stone Quarry
⛰️ Architecture Born from Nature
Built between 1906 and 1912, Casa Milà — known locally as La Pedrera (“The Stone Quarry”) — marked the peak of Gaudí’s creative freedom. The undulating stone façade, wrought-iron balconies, and self-supporting structure defied architectural conventions.
🌌 The Rooftop Warriors
Its surreal rooftop is one of the most photographed spots in Barcelona. The chimneys and ventilation towers, shaped like helmeted warriors, create a landscape that feels like a dream between art and science fiction.
🪟 Innovation and Functionality
Casa Milà was revolutionary: it featured an internal courtyard for light, an underground garage (unheard of at the time), and free-flowing apartments without load-bearing walls — proof that Gaudí was far ahead of his time.
🕰️ A Living Cultural Space
Now managed by the Fundació Catalunya La Pedrera, Casa Milà serves as a cultural center, hosting exhibitions, concerts, and educational programs — keeping Gaudí’s spirit alive.

🌍 UNESCO Recognition
Both Casa Batlló and Casa Milà form part of the collective UNESCO World Heritage Site “Works of Antoni Gaudí,” a designation that honors seven of his most exceptional creations. This list also includes his seminal project, Sagrada Família: The Iconic Masterpiece of Barcelona, and the colorful public park, Park Güell: Gaudí’s Colorful Masterpiece in Barcelona. Recognized in 1984 and extended in 2005, this status highlights their outstanding universal value — not only as architectural masterpieces but also as symbols of human creativity and innovation.
These buildings exemplify Gaudí’s genius in merging art, nature, and structure, redefining what architecture could be at the turn of the 20th century. Their inclusion in the UNESCO list ensures their preservation for future generations, allowing visitors from around the world to witness how Gaudí transformed Barcelona into a living museum of imagination and modernist beauty.
