1. What is the Cathedral of Santa Eulalia?

The Cathedral of Santa Eulalia is a church dedicated to Saint Eulalia, the patron saint of Barcelona. It is known as the most prestigious church in Barcelona and is officially named the “Cathedral of the Holy Cross and Saint Eulalia.”

Locals in Barcelona affectionately refer to it as “La Seu.” Construction of the cathedral began around the end of the 13th century, and the initial structure was completed in 1450—about 150 years later. At first, it was a simple church with no reliefs or decorations, but for the 1888 Barcelona Universal Exposition, the façade was expanded, transforming it into the magnificent cathedral we see today.
Walking around the church, you’ll notice several parts that still retain traces of the original construction. As a historically significant site that has witnessed over 700 years of Barcelona’s history, it is certainly worth visiting. Its beauty and grandeur are sure to leave a lasting impression.
2. The Mausoleum Where Young Eulalia Rests
Beneath the main altar in the cathedral’s underground crypt lies the coffin of young Eulalia, who was martyred at just 13 years old. Born in Barcelona in the year 290 AD, Eulalia was a devout Christian. At that time, the Roman Empire, which ruled over Barcelona, was harshly persecuting Christianity, considered a new and growing religion. Eulalia refused to renounce her faith, and as a result, endured 13 tortures before being executed at the age of 13.
Her remains were later buried in the cathedral. On February 12, designated as “Saint Eulalia’s Day,” the gates of the underground mausoleum are opened, allowing visitors to enter. A grand parade and festival are also held on this day, so it’s well worth timing your visit accordingly.
3. 28 Small Chapels

Inside the cathedral, 28 small chapels are arranged as if surrounding the structure. The golden altars, adorned with dazzling decorations, are dedicated to Christ and various saints. Worshippers who attend mass visit and pray at the chapels of the saints they hold dear.

In the chapel at the far left corner, you’ll find a statue of the Black Madonna, affectionately known as “La Moreneta” (“the little dark one”). Much like the Black Madonna of Montserrat, a renowned spiritual site, it is said that prayers offered here may be granted. Being the most popular chapel, candles are always burning at this spot.
4. The 13 Geese Kept in the Courtyard

As you walk through the cloister beyond the cathedral, you’ll come across a courtyard filled with palm and orange trees. In the pond within this courtyard live 13 geese. These geese are kept here in reference to Saint Eulalia, who once tended geese and who, according to legend, endured 13 tortures and was martyred at the age of 13.
5. A Majestic Exterior That’s a Popular Photo Spot

Although the Cathedral of Santa Eulalia is still relatively unknown as a tourist destination, once you visit, you’re sure to be captivated by its beauty. While most of the attention in Barcelona tends to go to Gaudí’s works, the cathedral’s neo-Gothic style and imposing architecture are truly breathtaking.
The interior is brilliant and ornate, but don’t miss the intricately crafted exterior, including the relief-covered walls, façade, and roof. You might even spot a unicorn on the rooftop—currently trendy and a hidden gem for photography lovers. It’s a lesser-known photo spot that’s worth visiting.
6. “Festival of Saint Eulalia,” Barcelona’s Winter Celebration

Every year on February 12, the “Day of Saint Eulalia” is celebrated with several days of festivities. Because the patron saint was martyred at age 13, many of the events are geared toward children. Highlights include parades of large “gegant” puppets, dance performances, and human pyramids, turning the entire city into a festive scene.
At night, the main event—the Fire Festival—is held at the Cathedral Square. This wild celebration involves people running around with firecrackers, and it’s considered one of the two major festivals of Barcelona alongside the autumn “La Mercè” Festival. This traditional celebration dates back to around the 18th century—don’t miss the chance to experience it!
◎ Don’t Miss the Renaissance-Era Pipe Organ!
The Cathedral of Santa Eulalia houses a pipe organ built in the 16th century. Most instruments from this period were made in Germany or Austria, but the one in this cathedral is Spanish-made! It even features horizontal pipes. Though it underwent restoration in the late 20th century, the organ itself is more than 450 years old. It’s a rare and historically rich instrument not often seen elsewhere.
