Castells ( Castell )

A castell (Catalan pronunciation: [kəsˈteʎ]) is a human tower built traditionally at festivals in Catalonia, the Balearic islands and the Valencian Community. At these festivals, several colles castelleres (teams that build towers) attempt to build and dismantle a tower's structure. On 16 November 2010, castells were declared by UNESCO to be amongst the Masterpieces of the Oral and Intangible Heritage of Humanity.
