Antoni Gaudí (1852-1926) spent almost his entire life working in Barcelona, and he left behind seven buildings throughout the city that UNESCO recognized as a World Heritage Site. These buildings are not alike: the Sagrada Família is a basilica that has been under construction for over 140 years, Casa Batlló looks as if it came from a fairytale, and Park Güell initially started as a luxury development that no one wanted to buy. What they have in common is a way of building that defied almost all the conventions of its time.
And 2026 is undoubtedly the best time to explore his work. June 10th marked the centenary of his death, and, coincidentally, the exterior of the central tower of the Sagrada Família had been completed just a few months prior. Furthermore, Barcelona is the World Capital of Architecture this year, a title awarded by UNESCO and the International Union of Architects. We'll delve into this further below.
Masterpieces: Where to begin
If you're visiting Barcelona for the first time, there are four main attractions that draw the vast majority of visitors. It's a good idea to know what you're going to see at each one before you book, because they require different amounts of time and different types of tickets.
Sagrada Familia
The Sagrada Família is the work that Gaudí did not live to see completed, and to which he dedicated his last 43 years. Since October 27, 2025, it has been the tallest church in the world, surpassing the 161.53 meters of the Ulm Minster; on February 20, 2026, the last piece of the cross was placed, and the tower of Jesus Christ reached its final height of 172.5 meters. Inside, the columns branch out like trees, and the light enters, tinted by hundreds of stained glass windows. Here, we tell you its history, its architecture, and how to get tickets.
Park Güell
Park Güell was meant to be a housing development for well-off families and ended up as a public park. Of the sixty plots put up for sale, only one was sold to a buyer from outside the project: the lawyer Martí Trias i Domènech, in 1902, who on top of that commissioned his house from another architect. The second house to be built was the developer's show house, which found no buyer; it was acquired by Gaudí's father in 1906, and the architect lived there for almost twenty years. What remains of that failed plan are the stairway with the trencadís salamander (which almost everyone calls “the dragon”), the undulating bench on the square and the hall of eighty-six columns. You pay for the Monumental Zone; the rest of the park is free. We explain what to see and how to visit it.
Batlló House
The Casa Batlló, located on Passeig de Gràcia, is a renovation that Gaudí carried out between 1904 and 1906 on a building that already existed. The facade is covered in ceramics and glass, the balconies resemble masks, and the roof imitates the back of a dragon; many people see in it the legend of Saint George. It is the most visually impressive of the four and also the shortest visit. See its history and details of the visit.
Casa Milà – La Pedrera (also known as La Pedrera)
The Casa Milà, better known as La Pedrera ("the quarry") because of its undulating stone facade, was Gaudí's last civil building. What almost no one forgets is its roof, with chimneys that look like warriors in helmets. Unlike the Casa Batlló, here you visit a floor furnished as it was lived in in 1910, and that changes the experience quite a bit. You can find everything on its page about history, architecture, and visit.
What is listed on the UNESCO World Heritage List, and what is not
Here's a common misunderstanding that appears in almost all guides. It's often read that "the Sagrada Familia is a World Heritage Site," which is not entirely accurate. The site is called "Works of Antoni Gaudí", it has number 320 on the UNESCO list, and it consists of seven components. Only the crypt and the Nativity façade of the Sagrada Familia are listed, which are the parts that Gaudí built with his own hands. The towers completed in this century, including the one of Jesus Christ, are outside the protected area.
| Work | Where is it? | What's registered | Year |
|---|---|---|---|
| Park Güell | Barcelona, Gràcia | The area | 1984 |
| Palau Güell | Barcelona, El Raval | The building | 1984 |
| Casa Milà (La Pedrera) | Barcelona, Passeig de Gràcia | The building | 1984 |
| Casa Vicens | Barcelona, Gràcia | The building | 2005 |
| Sagrada Familia | Barcelona, Eixample district | Only the crypt and the facade depicting the Nativity | 2005 |
| Batlló House | Barcelona, Passeig de Gràcia | The building | 2005 |
| Crypt of the Colònia Güell | Santa Coloma de Cervelló | Only the crypt | 2005 |
The list has another peculiarity that is worth noting: it does not match the list of buildings that can be visited. The Torre Bellesguard can be visited, but it is not listed. The Palau Güell has been listed since 1984, and of the seven, it is the one that receives the fewest visitors. If you are looking for the stamp, this is the list; if you are looking for what to see, the list is different.
Beyond the major icons
Those four names don't tell the whole story. Gaudí left other works in Barcelona that are less crowded and have a cheaper entrance fee. The Casa Vicens, in the Gràcia neighborhood, was his first important house and wasn't opened to the public until 2017. The Palau Güell, near Las Ramblas, is where he learned to play with light and to finish the chimneys with colored ceramics. There's also the Torre Bellesguard, with a nearly medieval feel, built on the ruins of a royal castle, and the crypt of the Colònia Güell, the laboratory where he tested the solutions he would later use in the Sagrada Família. We review them in more Gaudí works in Barcelona.
If you're traveling on a tight budget, there's quite a lot of Gaudí you can see for free from the street: the lampposts he designed for Plaça Reial, the dragon gate of the Pavellons de la Finca Güell, or the façades on Passeig de Gràcia. We've gathered them in the hidden Gaudí guide.

The Gaudí Route, beyond Catalonia
It's hard to imagine Gaudí working far from Barcelona, but he did. In Comillas (Cantabria), he built El Capricho, a summer house covered in ceramic sunflowers. In León, he constructed the Casa Botines, now a museum, and in Astorga, the Palacio Episcopal, which looks more like a castle than a bishop's palace. These are three stops that form a little-traveled route through northern Spain, and we tell you about it in El Camino de Gaudí.
Who was Antoni Gaudí?
Gaudí wasn't just a decorator with good taste; he was a builder obsessed with geometry and with the way things stand upright. He studied bones, trees, and shells to solve structural problems, and he sought to have a building stand on its own form rather than supporting it with buttresses. He worked more with models than with blueprints, although blueprints existed: in fact, they burned in 1936. This way of thinking has a name and a period: Catalan Modernism, the local version of Art Nouveau. To understand it better, start with his biography, then explore the Gaudí method and his relationship with Catalan Modernism.
Originality lies in returning to the source.
Gaudí: Dates
These are the years that explain why Barcelona is the way it is. The construction dates are provided by the organizations that oversee each building; when there are discrepancies between sources, we note this on the page for that particular building.
The origins
June 25, 1852
Antoni Gaudí was born
Whether in Reus or Riudoms: the Vatican decree of 2025, which declares him venerable, states "probably in Reus," and the question remains open. He was the son and grandson of blacksmiths, and he grew up watching how metal was shaped.
1878
Title: Architect
The tradition says that the director of the school, Elies Rogent, when presenting him with the degree, said he didn't know if he was awarding it to a madman or a genius. This story is passed down in about half a dozen different versions, and there is no primary source to support it. That same year, he met Eusebi Güell.
1883
Casa Vicens and the Sagrada Familia
At 31 years old, with five years of experience, she embarks on her first major project, inheriting a building that another architect had left unfinished. She completely redesigns the project.
The growth
1886-1890
Palau Güell
The commission that Güell gave him allowed for an almost unlimited budget, right in the heart of the Raval district. Here, we see the perforated dome, resembling a starry sky, and the ceramic chimneys, which he would later repeat in other projects.
1900-1914
Park Güell
Fourteen years of construction for a housing development that failed to attract buyers. The city council purchased it in 1922 and opened it as a public park on April 26, 1926.
1904-1912
Casa Batlló and La Pedrera
His two buildings on Passeig de Gràcia are located one behind the other. He has disputes with the city council regarding the Casa Milà's excessive volume, and with the property owner regarding fees.
1914
Only the temple
He abandoned everything else and dedicated himself exclusively to the Sagrada Familia. He eventually ended up living in the workshop of the project itself.
June 10, 1926
Died in Barcelona
A tram had hit him three days earlier on Gran Vía. He was poorly dressed and had no identification, and they mistook him for a homeless person. Out of the eighteen towers planned for the temple, he had seen the completion of one.
Today
1936
Workshop on fire
During the Civil War, the blueprints and photographs were burned, and the plaster models were destroyed. The fact that the project could continue is due to two things: the fragments of plaster were collected and sorted, and the most important blueprints had already been published in the ten years prior.
1984 and 2005
UNESCO
First, Park Güell, Palau Güell, and Casa Milà were designated. Twenty-one years later, Casa Vicens, Casa Batlló, the crypt of the Colònia Güell, and the two sections of the Sagrada Família that he built were added to the list.
2026
The centenary
On February 20th, the exterior of the Christ the King tower was completed, reaching a height of 172.5 meters. On June 10th, exactly one hundred years after his death, Pope Leo XIV presided over the centennial mass and blessed the tower.
2026: The centenary of Gaudí
On June 7, 1926, a tram from line 30 struck Gaudí at the intersection of Gran Via and Bailèn. He died three days later, on June 10, and at first, no one recognized him: due to his worn clothing, he was mistaken for a beggar. A hundred years later, 2026 has become the Year of Gaudí, a designation given to it by the Generalitat de Catalunya.
The date coincided with two milestones. In February, the last piece of the cross on the tower of Jesus Christ was installed, and on June 10th, Pope Leo XIV presided over the solemn mass in the basilica and blessed the tower, which was illuminated for the first time that night. A year earlier, in April 2025, the Vatican had declared Gaudí venerable: this is the first step on the path to sainthood, and a recognized miracle is needed to move to the next stage. We have gathered the events and news on the centennial 1926-2026 page.
How to plan your visit
Before you book, here are four tips to avoid disappointment:
- Book your tickets for the Sagrada Familia and Casa Batlló well in advance, as they tend to sell out quickly.
- At Park Güell, entry is timed; if you arrive late, you will miss your designated time slot.
- The four major works are located throughout the city, but Casa Batlló and La Pedrera are situated close to each other, just a five-minute walk apart.
- If you only have one day, choose wisely: visiting both the Sagrada Familia and Park Güell together will take up an entire day, including travel time.
Depending on the number of days you have, we have prepared a Gaudí route that can be completed in 1, 2, or 3 days, and a guide to combined tickets and discounts so you don't overpay. All the practical information is available on our plan your visit page.
