A castell (Catalan pronunciation: [kəsˈteʎ]) is a human tower built traditionally in festivals at many locations within Catalonia. At these festivals, several colles castelleres (groups who construct towers) often succeed in building and dismantling a tower's structure.
A castell is considered a success when assembly and disassembly can be done in complete succession. The assembly is complete once all castellers have climbed into their designated places, and the enxaneta climbs into place at the top and raises one hand with four fingers erect, in a gesture said to symbolize the stripes of the Catalan flag. The enxaneta then climbs down the other side of the castell, after which the remaining levels of castellers descend in highest to lowest order until all have reached safety. (Taken from Wikipedia)
