During the Fiesta de la Merce in Barcelona, various traditional dances are performed, including the Sardana and Giga. The Sardana is a collective dance characterized by its circular formation, where dancers hold hands and perform synchronized steps, symbolizing unity and community. The Giga is faster-paced and involves lively music often accompanied by colorful costumes and energetic movements. These dances are not only a celebration of local culture but also serve to connect attendees through shared heritage and celebration of Barcelona's history and traditions.
