Our journey through Barcelona begins with two of Antoni Gaudí's most famous works - the Sagrada Familia and Park Güell. These remarkable sites not only define the city's skyline, but also embody the vision and genius of their creator.

The Sagrada Familia, whose construction began in 1882 and continues to this day, is a symbol of Barcelona and one of the most extraordinary churches in the world. This basilica combines elements of Gothic and Art Nouveau to create a unique style that delights and intrigues. The temple's facades, such as the Façade of the Nativity and the Façade of the Passion, are full of symbolism and detail that can be admired for hours. The interior of the basilica is breathtaking - the tree-like columns, the amazing play of light thanks to the colorful stained glass windows, all create a mystical atmosphere. It's worth buying tickets online in advance to avoid long queues. Ticket prices range from 26 to 40 euros for adults (as of 2023), depending on the tour option chosen.

Park Güell, on the other hand, located on El Carmel hill, is a fairy tale land that transports you to the world of Gaudí's imagination. Originally planned as an exclusive housing development, this remarkable urban park is today one of the most popular places in Barcelona. The famous mosaic salamander ('el drac'), an undulating bench covered with colorful tiles or a colonnade resembling a forest are just some of the attractions that await visitors. The observation deck offers a beautiful panoramic view of the city. Park Güell is the perfect place to take a relaxing stroll and discover unusual architectural forms. Admission tickets cost about 10 euros for adults (price of 2023), and are best purchased online by selecting a specific time of entry.

Both the Sagrada Familia and Park Güell are UNESCO World Heritage Sites, highlighting their unique cultural and artistic value. Both places offer unforgettable experiences, but differ in character - the Sagrada Familia impresses with its majesty and spiritual atmosphere, while Park Güell captivates with its fairy-tale scenery and natural forms. Whether you're a lover of architecture, art or simply looking for beautiful views, these two places are sure to become highlights of your visit to Barcelona.

Continuing our journey in the footsteps of Antoni Gaudí, we can't leave out two remarkable townhouses that revolutionized Barcelona's residential architecture - Casa Batlló and Casa Milà. Both buildings, located on the elegant Passeig de Gràcia, are perfect examples of Catalan modernism and show how Gaudí was able to transform ordinary residential houses into true works of art.

Casa Batlló, often called the 'House of Bones' because of its organic shape, is a true architectural gem. The building's facade resembles the surface of a rolling ocean, with balconies like masks or skulls and colorful mosaics that sparkle in the sunlight. The interior is equally fascinating - curved lines, spiral staircases, amazing stained glass windows and thoughtful details create a magical atmosphere. The tour is guided by an augmented reality audio guide, giving an even better understanding of the building's concept and history. Admission tickets cost between €25 and €35 for adults (2023 prices), depending on the tour option chosen.

Just a few blocks away is Casa Milà, also known as La Pedrera ('The Quarry'), for its unusual, undulating facade. This building, designed between 1906 and 1912, impresses with its combination of architecture and nature. The interior of Casa Milà is a veritable maze of winding corridors and unusual rooms. But the real highlight is the building's roof, where there are distinctive chimneys shaped like surreal sculptures, often compared to knights in helmets. The roof also offers a beautiful view of Barcelona. An entrance ticket costs about 24 euros for adults (as of 2023).

Both buildings, Casa Batlló and Casa Milà, are UNESCO World Heritage Sites and are must-see spots on any architecture lover's map. However, they differ in style and atmosphere - Casa Batlló is more fanciful and colorful, while Casa Milà impresses with its monumentality and austere beauty. Casa Batlló offers a more interactive tour experience thanks to augmented reality technology, while Casa Milà allows you to explore the interiors more freely and enjoy the city skyline from the rooftop.

Visiting both buildings is not only a lesson in architectural history, but also an opportunity to immerse yourself in the world of Gaudí's imagination. Every detail, every line and curve has its own meaning and function, making these buildings not only beautiful, but also extremely functional. It's worth reserving at least half a day for a thorough tour of both sites to fully appreciate their beauty and innovation.

Our Barcelona trip would not be complete without a visit to the heart of the Old Town - the Cathedral of St. Eulalia, also known as the Barcelona Cathedral. This monumental work of Gothic architecture stands in contrast to Gaudí's modernist creations, but is equally fascinating and rich in history.

St. Eulalia Cathedral, whose construction began in the 13th century and took more than 150 years, is dedicated to the city's patron saint, St. Eulalia, a young girl who died a martyr's death during a period of persecution of Christians. The façade of the cathedral, despite the fact that it was completed only in the 19th century, perfectly harmonizes with the Gothic style of the whole. The impressive towers, soaring arches and richly decorated portals catch the eye and impress with their majesty.

The interior of the cathedral is just as impressive as its exterior. The high vaults, beautiful stained glass windows and numerous side chapels create an atmosphere of concentration and spirituality. Of particular note is the crypt of St. Eulalia, which houses the relics of its patron saint, and the choir with its richly carved stalls.

One of the most distinctive features of the cathedral is its cloister, where.... is home to 13 white geese. The number symbolizes the age of St. Eulalia at the time of her martyrdom. This unusual combination of the sacred with an almost fairy-tale element gives the cathedral a unique character.

From the roof of the cathedral, there is a beautiful view of the Barri Gòtic (Gothic Quarter) and all of Barcelona. There is an additional fee to take the elevator up to the roof, but it is definitely worth the price because of the panorama that unfolds from there.

Admission to the cathedral is charged for tourists (about €9 for adults, as of 2023), but you can enter for free in the morning to attend Mass. It's worth remembering that tours are limited during this time.

Compared to Gaudí's works, St. Eulalia Cathedral represents a completely different style and era. While the Sagrada Familia or Casa Batlló impress with their innovation and fanciful forms, the cathedral impresses with its classical beauty and rich history. It is a place that allows you to travel back in time to medieval Barcelona and feel the spirit of this remarkable city.

To sum up our tour of Barcelona's most iconic attractions, it is worth noting how diverse and fascinating the city is. From Gaudí's futuristic visions to the majestic Gothic of the cathedral, each site tells a different story and allows you to see Barcelona from a different perspective. Whether you're a lover of architecture, history or simply looking for beautiful views and an unforgettable experience, Barcelona has something for everyone. It is a city that not only impresses with its beauty, but also inspires and leaves an indelible impression long after you return home.
