La Mercè is Barcelona's patron-saint festival and the city's biggest free party, five days when the streets themselves become stages across all ten districts. The 2026 guest city is Shanghai, the first from Asia, bringing around 110 artists including the Shanghai Acrobatic Troupe, and Chinese dragons dancing alongside Barcelona's own gegants. For families, Mercè Petita offers dedicated children's workshops, theater and circus, the daytime castellers and gegants parades in Plaça Sant Jaume suit small kids, a separate Correfoc Infantil gives a gentler fire run, and this year's closing piromusical launches from Barceloneta beach, visible from across the city.
More family picks, Friday to Sunday.
