La Mercè
La Mercè (officially Festa Major de Barcelona) is Barcelona's largest annual festival, celebrating the city's patron saint, Our Lady of Mercy. Held every year around 24 September, it transforms the city into a four-day programme of over 600 free events — world-class concerts, traditional Catalan folk displays, fire runs, human towers, and open-air parties across every neighbourhood.
