Sources: 2. Developments: 2. The Catalan tradition of ‘castells’, or human towers, is a cultural practice recognized by UNESCO as Intangible Cultural Heritage of Humanity. The construction of these towers involves a precise physical architecture consisting of the ‘pinya’ (base), the ‘tronc’ (central columns), and the ‘pom de dalt’ (top section), culminating with a child known as the ‘enxaneta’ signaling completion. While the practice is rooted in Catalonia and has expanded to international cities such as Paris, Boston, and Sydney, local organizational efforts are also underway. Five major casteller groups—Minyons de Terrassa, Castellers de Vilafranca, Colla Vella dels Xiquets de Valls, Joves Xiquets de Valls, and Jove Xiquets de Tarragona—have formed a unified candidacy to lead the Coordinadora de Colles Castelleres (CCCC). This alliance seeks to shape the future of the coordination body and strengthen the community through a twelve-member slate representing various geographic areas and levels of the tradition. ## Timeline ### 2026-08-15: Catalan castellers build human towers through physical precision The Catalan tradition of 'castells' involves building complex human towers through a precise organization of participants based on physical attributes.
