La Mercè Festival traditions
Gegants & Capgrossos
One of the highlights of the Mercè Festival is undoubtedly the Gegants and Capgrossos (giants and big heads), a renowned attraction and one to be enjoyed by the whole family!
Best described as tall papier-mâché figures worn by ‘giant carriers’, these characters perform dances while the parade makes its way through the streets of Barcelona. Here you’re sure to see an endless variation of creative and imaginative designs! An added bonus is that the Capgrossos often run at the crowds and interact, making for an all-round unforgettable Barcelona experience!
Dates and times: The City Giants’ route takes off from Plaça de St Jaume on Wednesday 23rd September at 10pm.

Correfoc
The ‘Fire Run’, also known as the Correfoc, is one of the most anticipated events during the Festes de la Mercè. Dragons, devils and various ‘bestiari de foc’ (fire beasts) perform dances and parades with fire while an estimated 80,000 fireworks are set off!
Don’t worry if you are visiting Barcelona with children as there is a ‘Little Devils’ fire run especially for younger kids, which usually kicks off a little earlier in the day.
Dates and times: On Saturday 26th September, from Passeig de Gràcia with Provença to Passeig de Gràcia with Consell de Cent. Starting at 8.30 and finishing around 11pm. The children’s fire run will take place earlier the same day from 6 to 7.45pm.

Castellers
One of the events that should definitely not be missed is the Castellers show! Also known as human towers, you are sure to find yourself enchanted by the Castellers as they climb up one another, sometimes as high as 8 stories, finishing off each structure with a small child climbing to the top of the tower.
An age-old custom dating back to the 18th century, this particular tradition originated in the province of Tarragona, located just outside of Barcelona. It is a well known fact that the top Castellers teams from all over Catalonia perform at La Mercè Festival, so you are definitely in for a treat!
Dates and times: Thursday 24th September at Plaça de Sant Jaume from 1 to 3pm.

La Sardana
One of the most Catalan traditions is practised throughout the region over La Mercè. This dance is one of Catalonia’s most recognisable traditional dances. Dancers join hands to form a circle and perform a precise sequence of steps to the music of a traditional cobla. This tradition is seen all over Barcelona and danced by people of all ages.
Dates and times: On Thursday 24th September, there will be Sardana dancing with the Associació Cultural Folkòrica Barcelona at Plaça de la Mercè from 6 to 7.45pm.

Live Music
If you’re a fan of live shows, then the concerts that run alongside the Mercè Festival are sure to satisfy your musical needs! Concerts BAM (Barcelona Acció Musical) hold a variety of performances by various international music groups, all gathered in Barcelona especially for La Mercè, as they have done for years!
