What it is

La Mercè is the major festival of Barcelona, a vibrant celebration that brings the city together each year in late September. Rooted in both religious devotion and local tradition, it honors the Virgin of Grace, the city’s patroness. Over the course of nearly a week, Barcelona’s streets, plazas, and parks transform into stages for hundreds of free events, from lively parades to concerts and performances. For locals, La Mercè is a cherished time to celebrate their city’s culture, history, and community spirit.

Where it comes from

La Mercè’s origins date back to the Middle Ages, with its roots in the veneration of the Virgin of Grace (Mare de Déu de la Mercè). In 1687, during a plague of locusts, Barcelona’s leaders asked the Virgin for help; when the city was spared, she was named its patroness, a title officially recognized by the Pope in 1868. The city government began organizing official festivities in 1871, and over time, La Mercè has grown into a major civic celebration, blending religious observance with Catalan cultural traditions.

How it is celebrated

La Mercè is marked by a dazzling array of events, many deeply tied to Catalan heritage. Traditional parades feature giant papier-mâché figures (gegants i capgrossos) and mythical characters, accompanied by drumming and music. The Sardana, a circle dance from Empordà, is performed in public squares. Castellers, or human towers, are a highlight, showcasing teamwork and skill as groups build intricate human structures. More recent additions include the Correfoc, where participants dressed as devils run through the streets with fireworks, and the Pyro-musical, a grand finale of fireworks, music, and water at Montjuïc. The festival also hosts a Catalan Wine Fair, a 10 km race, and a “Guest City” program inviting artists from abroad.
