Sagrada Familia
Barcelona · Catalonia · church · ★ 4.8 · 326,411 reviews ·
Open in Google Maps ↗Basílica i Temple Expiatori de la Sagrada Família, or simply Sagrada Família, is a Catholic church that was under construction in the Eixample district of Barcelona, Catalonia, Spain. Designed by the Catalan architect Antoni Gaudí, it is the tallest church
in the world. On 7 November 2010, Pope Benedict XVI consecrated the church and proclaimed it a basilica. In 2005, parts of the Sagrada Família (Nativity façade and Crypt) were declared a UNESCO World Heritage Site, under "Works of Antoni Gaudí".
On 19 March 1882, construction of Sagrada Família began under the architect Francisco de Paula del Villar. In 1883, when Villar resigned, Gaudí took over as chief architect, transforming the project with his architectural and engineering style, combining Gothic and curvilinear Art Nouveau forms. Gaudí devoted the remainder of his life to the project, and he is buried in the church's crypt. At the time of his death in 1926, less than a quarter of the project was complete.
Relying solely on private donations, Sagrada Família's construction progressed slowly and was interrupted by the Spanish Civil War. In July 1936, anarchists from the Iberian Anarchist Federation (Federación Anarquista Ibérica, or FAI) set fire to the crypt and broke their way into the workshop, partially destroying Gaudí's original plans. In 1939, Francesc de Paula Quintana took over site management, which was able to go on with the material that was saved from Gaudí's workshop and that was reconstructed from published plans and photographs. Construction resumed with intermittent progress in the 1950s. Advancements in technologies such as computer-aided design and computerised numerical control (CNC) have since enabled faster progress, and construction passed the midpoint in 2010. In 2014, it was anticipated that the building would be completed by 2026, the centenary of Gaudí's death, but this schedule was threatened by work slowdowns caused by the COVID-19 pandemic.
The central Tower of Jesus Christ reached structural completion on 20 February 2026, when the final piece was installed, and it was inaugurated and blessed by Pope Leo XIV on 10 June 2026 during his visit to Spain, coinciding with the centenary of Gaudí's death. The tower, with a height of 172.5 m (566 ft), makes the Sagrada Família the world's tallest church.
Describing Sagrada Família, the art critic Rainer Zerbst said "it is probably impossible to find a church building anything like it in the entire history of art", and Paul Goldberger describes it as "the most extraordinary personal interpretation of Gothic architecture since the Middle Ages".
Though sometimes described as a cathedral, the basilica is not the cathedral church of the Archdiocese of Barcelona; that title belongs to the Cathedral of the Holy Cross and Saint Eulalia.

Casa Batlló
Barcelona · Catalonia · historical landmark · ★ 4.7 · 212,917 reviews ·
Open in Google Maps ↗Casa Batlló (Catalan pronunciation: [ˈkazə βəˈʎːo] ) is a building in the center of Barcelona, Spain. It was designed by Antoni Gaudí, and is considered one of his masterpieces. A remodel of a previously built house, it was redesigned in 1904 by Gaudí (although the actual construction had not begun at this point) and has been refurbished several times since. Gaudí's assistants Domènec Sugrañes i Gras, Josep Canaleta and Joan Rubió also contributed to the renovation project.
Casa Batlló is located on the Passeig de Gràcia in the Eixample district and forms part of a row of houses known as the Illa de la Discòrdia (or Mansana de la Discòrdia, the "Block of Discord"), so named because it features four striking, and strikingly different, buildings by noted Modernista architects of Barcelona.
Like everything Gaudí designed, Casa Batlló is only identifiable as Modernisme in the broadest sense. The ground floor, in particular, has unusual tracery, irregular oval windows and sculpted stonework with sinuous, squiggly forms. There are few straight lines, and much of the façade is decorated with a colorful mosaic made of broken ceramic tiles (trencadís).
In 2005, Casa Batlló became a UNESCO World Heritage Site.

Park Güell

Open in Google Maps ↗Park Güell (Catalan: Parc Güell [ˈpaɾɡ ˈɡweʎ]; Spanish: Parque Güell) is a complex of parks and gardens in Barcelona with architectural elements, located in the La Salut neighborhood of the Gràcia district in Barcelona, Catalonia, Spain. It is situated on the southern slope of the Turó del Carmel hill, part of the Collserola mountain range, overlooking the city. The separate Parc del Carmel lies on the northern side of the same hill.
In the context of Barcelona's late 19th and early 20th-century urban expansion, Catalan industrialist and art patron Eusebi Güell commissioned architect Antoni Gaudí, a leading figure of the aesthetic movement in Catalan modernism, to design a park.
Construction took place between 1900 and 1914, and the park officially opened to the public in 1926. In 1984, UNESCO designated the park a World Heritage Site, recognizing it as part of the "Works of Antoni Gaudí" collection and stating "the architecture of the park combined elements from the Arts and Crafts movement, Symbolism, Expressionism, and Rationalism, and presaged and influenced many forms and techniques of 20th-century Modernism."

La Pedrera - Casa Milà
Barcelona · Catalonia · ★ 4.6 · 112,481 reviews ·
Open in Google Maps ↗Casa Milà (Catalan: [ˈkazə miˈla], Spanish: [ˈkasa miˈla]), popularly known as La Pedrera (Catalan: [lə pəˈðɾeɾə], Spanish: [la peˈðɾeɾa]; "the stone quarry") in reference to its unconventional rough-hewn appearance, is a Modernista building in Barcelona, Catalonia, Spain. It was the last private residence designed by architect Antoni Gaudí and was built between 1906 and 1912.
The building was commissioned in 1906 by Pere Milà and his wife Roser Segimon. At the time, it was controversial because of its undulating stone facade, twisting wrought iron balconies, and design by Josep Maria Jujol. Several structural innovations include a self-supporting stone façade, and a free-plan floor, underground garage and the spectacular terrace on the roof.
In 1984, it was declared a World Heritage Site by UNESCO. Since 2013 it has been the headquarters of the Fundació Catalunya La Pedrera, which manages visits to the building, exhibitions and other cultural and educational activities at Casa Milà.
