Festa de la Ciència
to
Parc de la Ciutadella Passeig de Picasso, Barcelona

Two weeks of live science demonstrations on topics ranging from climate change to astronomy and botany will take over the city for the Festa de la Ciència. BioBlitz, a two-day event beginning on May 19th, will be held in the Montjuïc botanical gardens, where participants can attempt to identify every species in the park. And at the festival’s finale in Ciutadella Park, the weekend’s stargazing competition winners will be announced alongside live music, local gastronomy and educational activities for kids.
