Castell
A castell is a human tower formed by stacking participants known as castellers into a pyramid-like structure, typically reaching six to ten levels high, built by organized amateur groups called colles castelleres during public festivals in Catalonia.[1][2] The tradition originated in the late 18th century in Valls, Tarragona, as a competitive display of strength, balance, and coordination, evolving from folk dances and religious processions into a symbol of Catalan cultural identity and communal effort.[3] A castell is deemed successfully completed (cargat) when the topmost participant, the enxaneta—usually a child—climbs to the summit and raises all four limbs in the air, followed by the safe dismantling (descarrega) of the tower to the accompaniment of traditional gralla music and sardana dances.[1][4] In 2010, the practice was inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity, recognizing its role in fostering intergenerational participation, discipline, and social cohesion among participants ranging from children as young as five to adults over sixty.[1][5] Competitions such as the Concurs de Castells de Tarragona evaluate colles on tower height, stability, and execution, with notable achievements including the first pillar de 10 (ten-person single column) in 2015, highlighting ongoing innovations in technique and training.[2]
