Things To Do

Celebrated this year from September 23rd to 28th, the La Mercè festival program is packed with things to do and see. The streets will be filled with fire-breathing dragons, capgrossos (big heads), esbarts (traditional dance groups), bastoners (stick dancers), trabucaires (ancient armed bandits) and gegants (giants). The central parade, la calvacada de la Mercè on September 24th is a spectacle for the whole family. Effigies of kings, queens and other courtly figures spin and dance through the streets, towering above the crowds. Measuring up to four meters high, the gegants parade is a sight not to be missed. Then, you can set your sights even higher as the castellers build their dizzyingly tall human towers up to 10 levels high!

But if all the festivities of La Mercè get to be a bit too much, why not take a culture break? Many of the city’s museums observe the holiday with a jornada de portes obertes (open doors). Check out our interactive map above with all the locations that are throwing open their doors for free. You should note that because these visits are so popular, a number of locations either require or recommend that you reserve your ticket in advance so you're not left waiting in long lines or get stuck without a ticket.
