La Festa Catalana (Catalan Festival) celebrates Catalan traditions and festivities every Saturday throughout the summer. Situated in Plaça Nova against the impressive backdrop of Barcelona’s gothic cathedral, the festival welcomes visitors to witness human castles (castells), giants (gegants) and folk dancing (sardanes). This colourful festival encourages visitors and residents alike to grasp the rich culture of Catalunya, with an ample array of tradition and customs unique to the region.
