Architectural Features of the Cathedral

The Cathedral by the Sea in Barcelona, also known as Santa Maria del Mar, boasts a Gothic design that’s truly unique. As you explore this beautiful Roman Catholic church, you’ll be awed by its incredible proportions and architectural elements. 

Built between 1329 and 1383, it remains an important symbol of Catalonia’s maritime and mercantile history.

(Just keep in mind that this isn’t the same building as the Cathedral of Barcelona, which is in the Gothic Quarter and is much bigger).

Uniqueness of The Gothic Design

The Catalan Gothic style found in Santa Maria del Mar exhibits a unified, elegant design which is unusual in large medieval buildings. The church comprises of three naves and a single apse, with the longest nave adjacent to the main entrance to accommodate the dimensions of the cimborio. 

The structure demonstrates features typical of Catalan Gothic constructions, such as the efficient use of space and the elegant arrangement of proportions.

Another striking aspect of the design of this historical Barcelona monument is its lack of gargoyles, which were traditionally used in Gothic architecture as decorative, functional elements. Instead, you’ll find carefully crafted columns and expansive arches showcasing the emphasis on simplicity in Catalan Gothic style.

Importance of Stained Glass Windows

One of the features of Santa Maria del Mar that’s most likely to grab your attention is its stunning stained glass windows, particularly the impressive rose window above the main portal. These windows not only add magnificent splashes of color throughout the church, but they also have significant symbolic meanings within the Roman Catholic tradition.

Within the nave and side chapels, you’ll discover intricate stained glass windows depicting various biblical scenes and saints. These windows serve to inspire and educate the faithful, creating a sense of wonder and reverence. 

Additionally, the Baroque altar within the church is an important element, showcasing a fusion of artistic styles from different periods.

In case you can’t tell already, when you visit Santa Maria del Mar, you’ll be stepping into a world of architectural marvels and timeless beauty. From the unique Catalan Gothic design to the captivating stained glass windows, this historic cathedral truly is a testament to human artistry and devotion.

History of the Cathedral by The Sea in Barcelona

While the architecture of Santa Maria del Mar is literally jaw dropping, for me, its history is just as interesting, especially when you think of how long it’s been watching over Barcelona.

1. The Bastaixos Role

In 14th-century Barcelona, the construction of the Santa Maria del Mar church, also known as the Cathedral by the Sea, was a community effort. The Bastaixos were port workers who played a significant role in constructing the church. 

These workers volunteered their time and effort, transporting heavy stones and other materials for building the church from the nearby Montjuïc quarry to the construction site.

In fact, it was thanks to their hard work that the Cathedral took only 54 years to be built – which is an amazing achievement when you consider how long others take to be built (just ask the Sagrada Familia, which has been under construction for more than 140 years and counting).

And as you walk through the basilica, you can observe the stunning Gothic style and impressive stained-glass windows. Keep an eye out for various symbols of wealth and maritime trade scattered throughout, reflecting the thriving trade community of medieval Barcelona.

2. Berenguer de Montagut Influence

Berenguer de Montagut was the architect responsible for the design of Santa Maria del Mar. His influence on the church is evident in its distinctly Catalan Gothic style, known for its purity and unity. 

De Montagut made sure to create a spacious, light-filled, and harmonious interior by designing tall columns, large windows, and minimal ornamentation, setting it apart from other large medieval Gothic cathedrals.

3. Santa Maria del Mar Relevance

Santa Maria del Mar gained prominence as a symbol of Barcelona’s maritime and mercantile power in the 14th century. However, during the Spanish Civil War, the church fell victim to arson and suffered severe damage, including from a fire that destroyed all of its interior in 1936. 

Despite this, it continued to stand as a testament to the city’s resilience. In fact, after the war, significant restoration work was undertaken to bring the church back to its original state. 

Today, it remains an essential part of Barcelona’s cultural and historical landscape, and it’s regarded as an outstanding example of Catalan Gothic architecture. Visitors can certainly continue to appreciate its beauty and learn about its rich history during their visit.

Cathedral of the Sea in Literature and Pop Culture

The Cathedral by the Sea, Santa Maria del Mar, has captured the attention of various forms of media, including novels and TV series. 

One of the most famous literary works revolving around this beautiful church is Ildefonso Falcones’s novel “La Catedral del Mar.” This rich representation has expanded into the visual realm as well, with a popular Netflix series adaptation.

La Catedral del Mar by Ildefonso Falcones

La Catedral del Mar” is a historical novel by Spanish author Ildefonso Falcones. The story follows the life of Arnau Estanyol, a peasant who flees from his feudal lord and finds refuge in Barcelona. 

As he becomes a free man and eventually grows wealthy, the people in the Ribera neighborhood, home to many fishermen, decide to build the greatest temple in honor of the Virgin Mary: Santa Maria del Mar, or, in the novel, Saint Mary of the Sea. 

Through this symbol of devotion, love, and perseverance, Arnau and the other characters are able to explore themes of freedom and personal growth.

The Cathedral of the Sea: The Netflix Series

Expanding from the written pages of Falcones’s novel, Netflix brought the story of “La Catedral del Mar” into production as a TV series back in 2018. The series follows Arnau Estanyol through a variety of episodes, exploring the same themes of love, struggle, and the pursuit of freedom.

The symbolism inherent in the Cathedral of the Sea acts as a center-point for each character’s journey, highlighting the perseverance and determination needed to build such a monumental, spiritual structure.

I have to admit: I haven’t watched the Netflix series, although it got a ton of positive reviews, with many viewers commenting that they found the TV adaptation to be a loyal representation of the novel. 

Plus the adaptation also features scenes from other works by Ildefonso Falcones, like “Heirs to the Land”, so it’s truly a broad adaptation of his work.
