The Semana Grande of San Sebastián 2025—known interchangeably as Big Week or Great Week—is not just a festival; it’s a cultural phenomenon that has defined Donostia’s summers since the late 19th century. Born in 1876 as a modest celebration to boost local morale after the Carlist Wars, today it attracts over a million visitors eager to experience Basque traditions, world-class entertainment, and the electrifying energy of Spain’s northern gem.
As the city prepares for its Great Week (August 15–23, 2025*), the anticipation is palpable. Though the official program remains under wraps, the Semana Grande Donostiarra promises its iconic blend of fireworks, concerts, and folklore. Below, we dive into its history, 2025 highlights, and tips to make the most of San Sebastián’s Big Week.
A Brief History: From Humble Origins to Global Fame
The Semana Grande of San Sebastián began as a civic initiative to revive the city’s spirit after years of conflict. Early editions focused on regattas, bullfights, and religious processions. By the 20th century, it evolved into a celebration of Basque identity, adding fireworks (1924) and the cannon shot ceremony (1934), now its most iconic traditions.
Post-Franco, the festival embraced modernity. The concerts in Sagues debuted in the 1980s, turning the neighborhood into a music hotspot, while international fireworks teams joined the competition in the 1990s. Today, the Great Week balances heritage with innovation—think drone shows alongside traditional txistu (Basque flute) performances.
What to Expect During the Semana Grande of San Sebastián 2025
While the full schedule will drop closer to summer 2025, these staples are guaranteed:
1. Fireworks Over La Concha Bay
A cornerstone of the Big Week, the International Fireworks Competition transforms La Concha into a stage for pyrotechnic artistry. Eight teams from Spain, France, Italy, and beyond compete nightly (10:30 PM), launching displays synchronized to music. Locals claim the best views are from Mount Igueldo or a rented kayak on the bay. Pro tip: Arrive early—beaches fill up by 9 PM!
2. Concerts in Sagues: The Soundtrack of the Great Week
The Sagues neighborhood, a 10-minute walk from the Old Town, becomes the heart of the Semana Grande Donostiarra. Its open-air stage hosts 30+ free concerts spanning rock, jazz, electronic, and Basque folk. Past lineups have included local legends like Berri Txarrak and international acts like The Pretenders. For 2025, rumors hint at a tribute to Donostia’s 150th anniversary as a tourist destination.
3. The Cannon Shot: “Artillero, Dale Fuego!”
The Great Week officially begins at noon on August 15 with the cannon shot at Paseo Nuevo. Crowds gather to hear the mayor shout “Artillero, dale fuego!” (Gunner, fire!), followed by a thunderous blast and a shower of confetti. The ritual, inspired by maritime traditions, symbolizes the city’s rebirth—a must-see for first-time visitors.
4. Basque Sports & Street Theater
The Big Week honors rural Basque culture with Herri Kirolak (traditional sports):
- Stone lifting: Athletes hoist 100+ kg granite blocks.
- Wood-chopping contests: Axes fly in rhythmic precision.
- Regattas: Colorful traineras (fishing boats) race across the bay.
Meanwhile, giants, txalaparta (percussion) players, and street performers animate the cobblestone streets of Parte Vieja (Old Town).
Why the 2025 Edition Will Be Unmissable
The Semana Grande of San Sebastián 2025 coincides with the 150th anniversary of Donostia’s rise as a European leisure destination. While organizers keep surprises under wraps, insiders suggest:
- A drone light show complementing the fireworks.
- Expanded sustainability efforts: Reusable cups at concerts, solar-powered stages.
- A gastronomy corner showcasing Basque chefs’ pintxos (tapas) creations.

Cultural Impact: More Than a Party
The Semana Grande Donostiarra is a lifeline for local businesses, generating €50+ million annually. But beyond economics, it’s a celebration of Basque resilience.
