La Mercè Festival 2026 in Barcelona

Every September, Barcelona transforms into one huge festival venue for several days. The streets come alive with music, parades, performances by artists, traditional Catalan dances and colourful shows. In 2026, the La Mercè festival will take place from 23 to 27 September, while the main day of the celebrations traditionally falls on 24 September — the feast day of the city's patron saint, Our Lady of Mercy (Mare de Déu de la Mercè).

La Mercè is considered Barcelona's most important city festival and attracts hundreds of thousands of residents and visitors every year. Almost all events are free to attend, making the festival one of the main reasons to visit the Catalan capital in September.

History of the Festival

The history of La Mercè spans several centuries. According to local tradition, Barcelona was struck by a plague of locusts in 1687. The city's residents prayed to Our Lady of Mercy, and after the disaster came to an end, the city council proclaimed her the patron saint of Barcelona. This status was officially confirmed by Pope Pius IX in 1868.

The modern format of the city festival began to take shape in 1902, when a large-scale Festa Major featuring parades, traditional performances and a cultural programme was organised for the first time. It was then that many of the traditions that became symbols of the festival and have survived to the present day first appeared.

La Mercè Festival 2026 Programme

The organisers have already unveiled the programme for La Mercè 2026, which promises to be one of the largest in recent years. From 23 to 27 September, Barcelona will host more than one hundred concerts, theatre performances, circus shows, street performances, exhibitions and family-friendly events. For the first time, the celebrations will extend across all ten administrative districts of the city, while Parc de les Glòries will become one of the new venues, hosting part of the Mercè Arts de Carrer street arts programme.

The festival will open on the evening of 23 September with the traditional opening address (Pregó). In 2026, this honour has been entrusted to renowned Barcelona winemaker Antoni Falgueras and his daughter, sommelier Meritxell Falgueras. Following the opening ceremony, the first concerts, theatre performances and festive events will begin in different parts of the city.

On 24 September, the official feast day of Barcelona's patron saint, visitors can enjoy traditional parades, performances by artists, street theatre, family activities and numerous events celebrating Catalan culture. Over the following days, the festival will continue with evening concerts, light shows and spectacular fireworks displays. On 26 September, one of the festival's most anticipated events will take place — the famous Correfoc, which this year will begin with a new installation, Porta de l'Infern ("Gate of Hell"), created especially for the celebrations.

La Mercè will conclude on 27 September with a spectacular pyromusical show. In 2026, it will be held for the first time on Bogatell Beach (Platja del Bogatell), as the traditional venue at the foot of Montjuïc is temporarily unavailable due to construction works.

A special feature of this year's festival will be the participation of Shanghai as the guest city. As part of the cultural exchange, residents and visitors to Barcelona will have the opportunity to enjoy performances by Chinese musicians, theatre companies and artists, while also discovering the contemporary art and cultural traditions of one of Asia's largest cities.

Official La Mercè 2026 Poster

This year, the organisers unveiled an unusual official festival poster. It was created by Barcelona-based artist and muralist Cinta Vidal Agulló, renowned for her works in which familiar urban architecture is depicted from several perspectives at once.

Unlike a traditional poster, the 2026 artwork was created as a real wall mural covering approximately 33 m². Once the festival has ended, it will remain a permanent feature of the La Marina de Port – Francesc Candel Library in the Sants-Montjuïc district.

At first glance, the artwork resembles a fantasy map of Barcelona. However, on closer inspection, visitors can recognise the Cathedral of Barcelona, the Basilica of La Mercè, Plaça del Rei, Joan Miró's sculpture Woman and Bird, the city's parks, streets and dozens of small scenes from everyday life in Barcelona. According to the artist herself, the poster was deliberately designed to invite viewers to look at it again and again, discovering new details each time.

Traditions You Shouldn't Miss

Despite its modern concert programme, La Mercè remains a celebration of Catalan traditions.

During the festival, visitors can watch the famous Castellers — teams that build spectacular human towers. This tradition has been recognised by UNESCO as part of the Intangible Cultural Heritage of Humanity and is considered one of the symbols of Catalonia.

Equally spectacular are the Gegants i Capgrossos parades, featuring enormous figures of kings, knights, fairy-tale characters and historical heroes, who make their way through the city's streets accompanied by music.

Those looking for unforgettable experiences gather for the famous Correfoc, during which participants dressed as devils dance beneath fireworks and showers of sparks. For many visitors, this becomes the most memorable event of the entire festival.

Visitors can also enjoy performances by groups dancing the traditional Catalan sardana, with spectators often joining in the dance themselves.

What to Try

La Mercè is a great opportunity to discover Catalan cuisine. Food stalls usually offer local cheeses, jamón, cured sausages, seafood dishes, pastries and traditional sweets. Many restaurants prepare special festival menus, while Terra i Gust, a food festival dedicated to local produce and contemporary Catalan cuisine, traditionally takes place in Ciutadella Park.

Useful Information for Visitors

Most festival events are free of charge and take place outdoors. During La Mercè, Barcelona's city centre becomes much busier than usual, so it is advisable to book accommodation and transport tickets well in advance.

If you are planning a trip to Catalonia at the end of September, La Mercè is an excellent opportunity to experience Barcelona from a different perspective — not only as a city of world-famous architecture and beaches, but also as a place where local traditions are carefully preserved and transformed each year into a vibrant celebration for residents and visitors from around the world.
