Historical Background of La Diada (1714 Siege of Barcelona)
The Catalonia National Day, also known as La Diada, is a remarkable cultural event that takes place every 11th of September.
It is a day of immense significance for Catalonia, as it commemorates the region’s unique identity, history, and struggle for autonomy within Spain.
The roots of Catalonia National Day date back to the 11th of September, 1714, when Barcelona fell to the Spanish army during the War of Spanish Succession.
This event marked the loss of Catalan institutions and autonomy. Yet despite this defeat, the Catalan people have fiercely preserved their cultural heritage, transforming the memory of that loss into a lasting symbol of resilience.
Over time, the Generalitat de Catalunya — Catalonia’s government — has played a central role in keeping the spirit of La Diada alive through cultural activities, exhibitions, and concerts across the region.
Today, September 11th is recognised as a public holiday, when schools, businesses, and government offices close their doors so people can participate wholeheartedly in the festivities.
La Diada is marked by various activities and events that bring the spirit of Catalonia to life. One of the most notable aspects of this special day is the massive demonstration that fills the streets of Barcelona.
Thousands of Catalans come together, passionately waving Estelada flags, symbolizing their support for an independent Catalonia.

From Mourning to Celebration: How the Day Evolved
La Diada hasn’t always been celebrated in the same way. Originally a solemn act of remembrance, it gradually shifted into a celebration of Catalan pride and identity.
Here’s a Quick Timeline of Its Evolution:
1714 – Fall of Barcelona during the War of Spanish Succession; Catalan institutions abolished.
1800s – First unofficial commemorations held at key memorial sites like Fossar de les Moreres.
1886–1888 – Public remembrance began spreading, linked with the Barcelona Universal Exposition, giving the day wider cultural meaning.
1930s – During the Second Spanish Republic, La Diada was embraced as a symbol of Catalan autonomy.
1939–1975 – Under Franco’s dictatorship, the holiday was banned, and expressions of Catalan identity were repressed.
1976 – Massive demonstration in Barcelona after Franco’s death marked the revival of La Diada.
1980 – Officially declared a public holiday by the newly restored Generalitat de Catalunya.
Today – A dual event: a cultural festival celebrating language, traditions, and cuisine, and a political stage where calls for independence and greater autonomy are voiced.
This journey from mourning to celebration reflects how Catalans have transformed a painful historical defeat into a living expression of resilience and unity.
For many, La Diada is not just about remembering 1714, but about showing that Catalan identity endures — proudly and publicly.
How Catalans Celebrate Today
From dawn to dusk on September 11th, Catalonia transforms into a living festival of history, identity, and pride.
What was once a solemn memorial has evolved into a day where remembrance and celebration coexist.
Morning: Tributes and Memorials
Wreath-laying at the Rafael Casanova Monument (Barcelona, ~09:00) – Politicians, civic leaders, and citizens place flowers at the statue of Rafael Casanova, a commander during the 1714 siege.
Fossar de les Moreres – A sacred spot near Santa Maria del Mar church where those who died in the siege are honoured. A flame burns here continuously, reminding everyone of Catalonia’s losses and resilience.
Midday: Cultural Expressions
Castells (human towers) – Teams of castellers carefully build and dismantle dizzyingly high human towers, symbolising unity and strength.
Sardana dances – Circles of dancers, hand in hand, perform the traditional sardana, expressing equality and community spirit.
Street parades and poetry readings – Many neighbourhoods host performances that highlight the Catalan language and folklore.
Afternoon: Demonstrations and Rallies
Over the last decade, the day has taken on a strong political dimension.
Hundreds of thousands often gather in Barcelona and other cities for peaceful demonstrations, waving the red-and-yellow senyera and the star-studded estelada flags.
Themes vary by year — independence, autonomy, or cultural rights — but the sense of collective voice is always present.
Evening: Music and Festivities
Concerts at Arc de Triomf and Parc de la Ciutadella – Large open-air shows organised by civic associations like Òmnium Cultural. These feature Catalan rock, folk, and contemporary acts.
Local gastronomy – Families and friends gather to share dishes like pa amb tomàquet, botifarra sausages, and fideuà. Streets and balconies often display Catalan flags, making the whole city glow in yellow and red.
Visitor Tips:
Plan transport early – Metro and bus services may be rerouted due to demonstrations. Walking or cycling is often the easiest way to move around central Barcelona.
Arrive early to events – Memorials and concerts get crowded quickly; turning up an hour in advance helps secure a good spot.
Respect the political context – While many visitors enjoy the cultural side, remember that for locals this is also a deeply political day. Approach demonstrations with respect, even if you’re just observing.

Places to Experience La Diada
While La Diada is honoured throughout Catalonia, certain locations hold special meaning and offer the richest experiences for visitors.
Barcelona – The Heart of the Celebrations
Fossar de les Moreres – This memorial square near Santa Maria del Mar is one of the most symbolic sites of the day. A flame burns continuously to honour those who died during the 1714 siege. Each year, flowers are laid and moments of silence observed here.
Rafael Casanova Monument – Early morning tributes take place at this statue, with politicians and citizens paying homage to the defender of Barcelona.
Arc de Triomf & Parc de la Ciutadella – Expect large concerts, family activities, and civic events organised by groups like Òmnium Cultural. By evening, these areas are filled with music, speeches, and food stalls.
Girona – Traditional Sardana Dancing
The city of Girona embraces La Diada with vibrant displays of Catalan identity.
Dance groups perform the sardana in main squares, inviting locals and visitors alike to join hands in circular formations. The atmosphere is festive, with music echoing through the historic old town.
Tarragona – Fire Runs and Human Towers
Tarragona adds its own fiery twist to the celebrations with correfocs (fire runs), where performers dressed as devils chase through the streets with sparklers and fireworks — a thrilling experience best enjoyed from a safe distance.
The city also showcases castells (human towers), an awe-inspiring tradition symbolising strength and unity.
Beyond the Big Cities
Smaller towns across Catalonia mark the day with community events, concerts, and flag displays. While less crowded than Barcelona, they offer a more intimate way to experience Catalan pride and hospitality.
The Political Dimension & Etiquette
Although La Diada is filled with cultural pride and festive traditions, it also carries a deeply political meaning.
For many Catalans, September 11th is more than a holiday — it’s a day to express aspirations for greater autonomy or independence from Spain.
Peaceful Demonstrations
In recent years, large-scale demonstrations have become a defining feature of the day, especially in Barcelona.
Streets fill with people carrying the senyera (Catalan flag) and the estelada (pro-independence flag).
These gatherings are usually peaceful, highly organised, and family-friendly, though the size of the crowds can be overwhelming for newcomers.
Respectful Participation
Visitors are welcome to watch and even join in some of the cultural activities, but it’s important to remember that for many locals, La Diada is highly personal.
Here are a few etiquette tips:
- Be mindful of symbols – Flags, banners, and slogans represent strong political views. Take photos respectfully without mocking or dismissing their meaning.
- Listen, don’t debate – Political conversations can run deep. It’s better to listen with curiosity than to argue.
- Stay safe in crowds – Demonstrations can draw hundreds of thousands of people. Stick to the edges if you’d like to observe without being swept into the middle.
A Day of Dual Meaning
For some, La Diada is primarily a cultural celebration. For others, it is a political rallying point. Both perspectives coexist, and that balance is what makes the day so unique. As a visitor, acknowledging both sides with respect ensures a positive experience.
