His flowing forms, vibrant mosaics and dreamlike architecture are woven into its very fabric, giving Barcelona its unmistakable identity. From iconic landmarks such as the Sagrada Família and Park Güell to lesser-known works scattered throughout the city, his legacy is still very much present today.

Toggle1. The Sagrada Família: Gaudí’s masterpiece
The Sagrada Família is Gaudí’s most iconic work and the ultimate symbol of Barcelona. Construction began in 1882 and is still ongoing today, although completion is finally getting closer.
Inside, you’ll find the stunning “stone forest” of columns, where natural light filters through stained glass in constantly shifting colours. Every visit feels different depending on the time of day. Don’t miss the Nativity Façade either, one of the few sections Gaudí personally worked on, full of symbolism and intricate detail.

Why 2026 is such a landmark year for the Sagrada Familia
2026 marks a historic moment: the completion of the 172.5-metre Tower of Jesus Christ, the tallest part of the basilica. It is expected to be inaugurated on June 10, exactly 100 years after Gaudí’s death, a symbolic moment in its long history.
2. Park Güell: Gaudí’s kaleidoscopic wonderland
Park Güell is one of the world’s most iconic examples of modernist architecture, and one of Gaudí’s most photographed works. It was originally planned as an exclusive residential development, though the project never fully came to life as intended.
Today, it’s a vibrant mix of architecture and nature. Colorful mosaics, winding pathways, and organic shapes blend naturally into the hillside landscape. The views over Barcelona are among the best in the city. For a more relaxed visit, go early in the morning before the crowd arrives.
The story behind Gaudí’s famous lizard
At the entrance to Park Güell, you’ll find “El Drac”, the prismatic mosaic lizard that has become one of Barcelona’s most recognisable symbols. It is covered in trencadís mosaics, a signature Gaudí technique that uses broken ceramic tiles to create vibrant, textured patterns.
3. Casa Batlló: Gaudí’s most iconic modernist house
Nestled along elegant Passeig de Gràcia, Casa Batlló is one of Gaudí’s most striking creations.
Its façade looks like something straight out of a dream, with wave-like shapes, bone-like details and scales that shimmer in the light. The roof is often compared to the back of a dragon, a subtle nod to the legend of Sant Jordi, Catalonia’s patron saint.
Inside, everything revolves around light, movement, and organic forms.
Traveller’s tip
Casa Batlló is especially atmospheric in the evening, when the façade is softly illuminated.
4. Casa Milà (La Pedrera): Gaudí’s quintessential residential building
Casa Milà, better known as La Pedrera, was one of Gaudí’s final civil works. It stands out immediately thanks to its flowing stone façade and distinctive wrought-iron balconies.
The rooftop is the star of the show, where the chimneys look almost like sculptural figures. From here, you can even spot the Sagrada Família in the distance, a reminder of how connected Gaudí’s works are across the city.
Why La Pedrera was revolutionary
When it was built in the early 20th century, Casa Milà was groundbreaking because it had no load-bearing interior walls. This meant residents could freely adapt to the layout of their homes, something completely innovative at the time.
5. Palau Güell: an early masterpiece in the heart of the city
Just a stone’s throw from La Rambla lies Palau Güell, one of Gaudí’s earliest major commissions (1888). The city palace was built for the industrialist Eusebi Güell, Gaudí’s most important patron.
Inside, Gaudí was already experimenting with light, space, and decoration. It offers a fascinating glimpse into the early development of his distinctive style. The rooftop is especially striking, with its chimney stacks decorated in colourful ceramics and mosaics.
6. Casa Vicens: Gaudí’s first major commission
Completed in 1885, Casa Vicens was Gaudí’s first major project and clearly shows influences from Moorish and Oriental architecture. Located in the Gràcia district, this brightly coloured building feels quite different from his later works, but you can already see his fascination with ceramics, nature and intricate detail.
Today, Casa Vicens is a museum and one of Barcelona’s most underrated Gaudí sites.
7. Casa Calvet: Gaudí’s most restrained design
Among Gaudí’s more elaborate works, Casa Calvet on Carrer de Casp 48 feels noticeably more understated. Even so, subtle references to nature and modernisme can still be found in the façade, balconies and decorative details.
The building was designed for a textile manufacturer and even won Barcelona’s award for Best Building in 1900.
8. Bellesguard (Casa Figueres): a blend of Gothic and modernism
Less well known but well worth a visit, Bellesguard is a fascinating mix of Gothic influences and Gaudí’s signature modernist style, which gives it a very different feel from his other works.
The tower also stands on a historically significant site in the Sarrià-Sant Gervasi district, once home to the summer residence of King Martí I of Aragon.
9. Colònia Güell Crypt: Gaudí’s experimental workshop
Just outside Barcelona in Santa Coloma de Cervelló lies Colònia Güell, an industrial workers’ colony where Gaudí was commissioned to design a church. Although it was never fully completed, the crypt remains one of his most important experimental works.
Where did Gaudí test his ideas for the Sagrada Família?
In the Colònia Güell crypt, Gaudí experimented with leaning columns, organic shapes and innovative structural solutions. Many of these ideas would later be used in the Sagrada Família.
10. Colegio de las Teresianas: simple yet innovative
The Colegio de las Teresianas is one of Gaudí’s lesser-known works. He had to work with a limited budget and the strict, modest requirements of a religious school.
Even so, he managed to create an elegant and distinctive building using simple brickwork, which is still used as a school today.
