On November the 16th 2010, in Nairobi (Kenya), Unesco approved the inscription of human towers on the Representative List Of the Intangible Cultural Heritage of Humanity, giving then a universal recognition to this element.
The human towers candidacy had been driven by the Generalitat de Catalunya (Catalonia's autonomous government), the Coordinadora de Colles Castellers de Catalunya, the UNESCO Centre of Catalonia and the "Castells" magazine. It was launched in 2007 in Valls. The candidacy gathered a great social support, including a unanimous statement from the Catalan Parliament in 2008.(You can read the Unesco file regarding human towers here.)
