Every time I take students to Casa Batlló, I see the same reaction. They stop in front of the façade of Casa Batlló, look up slowly at the colours and shapes of Casa Batlló, and fall silent. Then come the smiles. Then the photos. And almost always, someone turns to me and says, “This is my favourite building in Barcelona.”
I have taken many students to Casa Batlló over the years, and the response is always the same. No matter their age or background, Casa Batlló leaves an impression that stays with them long after they leave Barcelona. There is something about Casa Batlló that feels alive, imaginative, and deeply connected to Barcelona and the wider world of architecture.

Discovering Casa Batlló in Barcelona
Casa Batlló is located at Passeig de Gràcia 43, in the heart of Barcelona. Passeig de Gràcia is one of the most elegant avenues in Barcelona, and Casa Batlló stands proudly on this famous street. When we walk along Passeig de Gràcia, I always point out how Casa Batlló transforms the entire block.

The location of Casa Batlló on Passeig de Gràcia places it at the centre of artistic competition. The block is known as the “Illa de la Discòrdia,” where different architects competed to design the most striking building. Yet Casa Batlló always captures the most attention.
From the moment visitors arrive at Passeig de Gràcia 43, they understand that Casa Batlló is not just another house. It is a building that completely changed the architectural landscape of Barcelona.

Antoni Gaudí and Total Creative Freedom
Casa Batlló was redesigned between 1904 and 1906 by Antoni Gaudí. The architect Antoni Gaudí was given total creative freedom by Josep Batlló and the Batlló family. That trust allowed Antoni Gaudí to completely transform the existing building into something revolutionary.
Josep Batlló wanted a unique residence for his family, and the Batlló family allowed Antoni Gaudí to reshape the façade, interior, roof, and every floor of the house. Thanks to that freedom, Casa Batlló became one of the most iconic buildings in Barcelona and in the world.
When I explain to students that Antoni Gaudí did not demolish the building but transformed it completely, they are amazed. It shows how imagination can reshape a structure into something extraordinary.
The Façade: Casa dels Ossos and the House of Bones
Casa Batlló is often called Casa dels ossos, meaning “house of bones” in Spanish and Catalan. The skeletal appearance of Casa Batlló gives it this nickname. The stone pillars look like bones, and the balconies resemble skulls. Students immediately notice the bones-like shapes in the façade.
The façade of Casa Batlló is covered in colourful tiles made using the trencadís technique. The glass and ceramic tiles reflect light beautifully. In certain moments, the façade is reminiscent of water lilies floating on the sea, full of movement and colour.
The organic shapes across the façade avoid straight lines. Instead, Antoni Gaudí created fluid forms inspired by nature. The building feels alive, almost like a dragon resting in the middle of Barcelona.

The Dragon Roof and the Legend of Saint George
One of the most exciting parts of every visit is when we look up at the roof of Casa Batlló. The roof is shaped like the back of a dragon, with curved tiles forming scales. The legend behind Casa Batlló connects to Saint George, the patron saint of Catalonia.
According to the legend, Saint George defeated a dragon to save a princess. The four armed cross at the top of the roof represents the lance of Saint George. The balconies below are said to represent the bones of the dragon’s victims.
The dragon appears again and again in the design of Casa Batlló. The roof terrace offers one of the best views of Barcelona, and from this roof terrace, students can clearly see the colourful tiles and the dramatic form of the dragon.
The legend of Saint George makes Casa Batlló more than architecture. It becomes storytelling carved into stone, glass, and tiles.

Inside the House: Light, Space and Innovation
Inside Casa Batlló, the magic continues. The ground floor welcomes visitors with flowing walls, curved wood details, and large glass windows that allow natural light to enter the space. The first floor, once the main residence of Josep Batlló and his family, is full of elegant details.
The interior of Casa Batlló shows Antoni Gaudí’s attention to air circulation, light, and comfort. The blue tiles in the central light well change shade as they rise, ensuring equal light distribution. Windows vary in size to balance the brightness from the lower part to the fifth floor.
The attic features beautiful catenary arches that create a space reminiscent of a ribcage or even a forest of curves. Below, the basement once contained water tanks that supported the house systems. Every floor of Casa Batlló was carefully designed, from the ground floor to the fifth floor.
Students are always surprised to learn that some apartments in Casa Batlló were rented, making the building both a family residence and a functional urban space.
Casa Batlló and the World Heritage Site Status
In 2005, Casa Batlló was declared a UNESCO World Heritage Site. This recognition confirmed that Casa Batlló is not only important for Barcelona, but for the world.
As a World Heritage Site, Casa Batlló represents innovation, creativity, and cultural identity. When students hear that Casa Batlló is protected at an international level, they understand that they are visiting something truly special.
