Thousands of people gather in Tarragona for a traditional Spanish Castells event in which groups compete to build human towers. The competition takes place in an old bullfighting ring, with participating castells teams attempting to construct the highest structures possible.
The event is held every two years and draws human tower groups from across Catalonia. Organisers stage the matchup as a high-stakes spectacle for participating teams and spectators, who watch as teams coordinate their climbs and formations.
Across coverage, the focus remains on the scale of attendance and the competitive nature of the tower-building. Sources also consistently place the event in Tarragona and describe it as part of a recurring Catalan tradition centered on teamwork, precision, and risk inherent in stacking people into tall formations.
