Sky show by arlequin_g
To celebrate the patron saint of Barcelona, Mercè, some events are held in the city during some days: castellets, concerts... One of them is the sky show where you can see planes performances and others. You can see it from Port Olimpic. It's during the end of September. Ask in the tourism office the day it takes place since it's not the same day each year.
