Casa Batllo vs Casa Mila: Two Gaudi Masterpieces, Five Minutes Apart
Antoni Gaudi built two iconic apartment buildings on Passeig de Gracia within five minutes’ walk of each other, and both rank among the most visited Gaudi sites in Barcelona. Casa Batllo (1904-1906) is a riot of colour, fantasy, and dreamlike forms; Casa Mila, also known as la pedrera barcelona (1906-1912), is a monumental wave of stone with a rooftop populated by surreal warrior-helmet chimneys. Together they represent the peak of Gaudi’s mature creativity. The question every architecture-curious visitor asks is: casa batllo or casa mila? Which one should you visit if you only have time for one?
This guide compares them across every dimension: architecture, interior experience, rooftop, ticket prices, opening hours, accessibility, photo opportunities, and ideal time of day. We also offer a clean recommendation for each visitor type at the end. Whether you visit one, both, or neither, by the end you will know exactly what each building offers and which is right for your trip.

Side-by-Side Comparison
Facade
Casa Batllo has a vivid, colourful trencadis (broken-tile mosaic) facade in shades of blue, green, and purple. The balconies are shaped like skulls or carnival masks; the columns at the lower windows resemble bones. The roof is undulating and tiled like dragon scales, with a turret topped by a small cross representing Saint George’s lance.
Casa Mila is a vast undulating wall of light limestone, with no straight lines anywhere. The wrought-iron balconies twist like sea creatures or tangled vines. The whole building looks like a wave, an iceberg, or a quarry; locals nicknamed it “La Pedrera” (the stone quarry) when it was built, intending it as an insult.
Interior Experience
Casa Batllo features the most technologically advanced museum experience of all Gaudi’s Barcelona buildings. The 2024-2025 renovation added a SmartGuide audio tour with augmented-reality overlays that show how rooms looked when the Batllo family lived there. The “Gaudi Cube” — a six-sided LED chamber — immerses visitors in a 360-degree visual journey through Gaudi’s design philosophy. The interior is bright, organic, and full of stained-glass colour effects.
Casa Mila offers a quieter, more historical experience. The interior includes the period-furnished Pedrera Apartment (showing how a wealthy 1910s Barcelona family lived), the Espai Gaudi attic exhibition (which uses Gaudi’s signature catenary arches and contains his original models), and the patio courtyards. The audio guide is included with all tickets and is excellent.
Rooftop
Casa Batllo’s rooftop has the famous dragon-scale tiling and a small viewing platform, but it is constrained in size and does not offer the dramatic 360-degree views of Casa Mila.
Casa Mila’s rooftop is one of the most extraordinary architectural spaces in Europe. The undulating surface is dotted with 30 chimneys and ventilation towers shaped like medieval warriors in helmets. Some chimneys are decorated with broken-glass champagne bottles. The 360-degree view stretches from the Sagrada Familia to the Mediterranean. This single space is the strongest argument for visiting Casa Mila.

| Wow factor | Interior + Gaudi Cube | Rooftop + chimneys |
| Photogenic | Facade + interior | Rooftop + facade |
Best for Photography
Casa Batllo is best photographed at the front facade in late afternoon golden light. The exterior is the most photogenic angle. Inside, the colour gradient through the patios is also iconic.
Casa Mila‘s rooftop is one of the great photo spots in Barcelona, especially at sunset. The chimneys silhouetted against the Sagrada Familia in the distance is the iconic shot.
Crowd Levels
Casa Batllo tends to be more crowded due to the augmented reality experience attracting families. Book the first slot of the day (9:00 AM) or the late evening slots (after 6:30 PM) for fewer crowds.
Casa Mila is slightly less crowded. The “Magic Pedrera” evening tour with light show on the rooftop is one of the most peaceful experiences and a personal favourite.
Accessibility
Both buildings are wheelchair accessible. Lifts reach the main floors and rooftops. Casa Mila’s rooftop has some uneven surfaces but is mostly accessible. Casa Batllo’s interior is fully accessible.
Which One Should You Visit?
Visit Casa Batllo if you…
- Want the most dramatic, immersive, technology-enhanced experience.
- Are travelling with children who enjoy interactive exhibits.
- Love bright colours and dreamlike imagery.
- Have a slightly higher budget.
- Want late-evening visiting hours.
- Are visiting in winter when daylight ends early.
Visit Casa Mila if you…

- Prefer a quieter, more historical visit.
- Want a slightly lower starting ticket price.
- Enjoy seeing how period-era apartments looked.
- Want to experience a Gaudi sunset or evening light show.

Visit Both if you…

The two buildings are only a 5-minute walk apart, so doing both in a single day is easy. The combined experience takes about 3 hours plus lunch.
Combined Visits: Buying Tickets for Both
Several third-party tour operators sell combined Casa Batllo + Casa Mila tickets, but the savings are usually minimal (5 to 10 EUR off the standard prices) and the time slots may be inflexible. We recommend booking each building’s official tickets separately for full flexibility.
Detailed Walkthrough: Casa Batllo
The Facade
The facade of Casa Batllo is one of the most photographed in Barcelona. The trencadis mosaic, the bone-shaped columns, the skull-balconies, and the dragon roof tell a coherent visual story: the legend of Saint George defeating the dragon, with the small cross-tipped turret representing the saint’s victory lance. Spend at least 10 minutes outside before going in.
The Noble Floor
The first stop inside is the noble floor (Planta Noble), the original Batllo family home. The doors, ceilings, fireplace, and stained-glass windows are all original Gaudi designs. The shape of the rooms mimics underwater grottos, with curved walls and ceiling effects designed to flow with movement.
The Patios
The patio interiors are coloured in a graduated tile scheme: deep blue at the top transitioning to white at the bottom. The result is a uniform light effect that compensates for the natural light fall-off in the central courtyard. The blue grows lighter as you descend, mimicking how water deepens.
The Loft and Roof
The loft features Gaudi’s signature catenary arches in white plaster, and the rooftop features the dragon-scale tiles and the cross-topped turret. A small viewing platform offers limited but charming views.
The Gaudi Cube
A six-sided LED chamber that immerses you in a 360-degree visual journey through Gaudi’s design philosophy. The 5-minute multimedia experience is included with most ticket levels and is the most technologically ambitious feature in any Gaudi museum.
Detailed Walkthrough: Casa Mila
The Facade
The undulating limestone wall has no straight lines and uses 6,000 cubic metres of stone. The wrought-iron balconies were designed by Josep Maria Jujol, Gaudi’s collaborator, who twisted iron into shapes that resemble seaweed or vines. Look up at the building from across Passeig de Gracia for the wave effect.
The Pedrera Apartment
A period-furnished apartment showing how a wealthy 1910s Barcelona family lived. Original furniture, kitchen, bedrooms, bathrooms, and reading rooms. The doorways and walls are organic curves; no straight angles anywhere.
The Espai Gaudi (Loft)
The attic is built around 270 catenary arches in brick, creating an undulating space that Gaudi himself called “his finest hidden room”. The exhibition includes original Gaudi models, photographs, and design tools. Allow 30 minutes here; serious architecture fans spend an hour.
The Patios
Two patio courtyards in pale stone and tile with curved staircase access to the upper floors.
The Rooftop
The headline experience. Climb the final stairs to find an undulating surface dotted with 30 chimneys and ventilation towers shaped like warriors in helmets. Some are decorated with broken champagne bottles (Gaudi’s trencadis aesthetic in 3D). The 360-degree views span the Sagrada Familia, the Mediterranean, the entire Eixample grid, and Tibidabo.
Special Experiences
Casa Batllo “Magic Nights”
Summer evening rooftop concerts with cocktails and live music. Book online; about 49 EUR.
Casa Mila “Magic Pedrera”
