A human pyramid is a type of stunt in which several participants stand or kneel together in a row or other formation, forming a base for another tier of participants who stand or kneel on their shoulders, backs or thighs. Successively smaller tiers of participants may be added, each tier supported by the one below it. Lighter participants are placed at the top of the formation, while the strongest participants form the base of the pyramid.
Foundation In a Catalan custom that is believed to date to the 18th century, colles castelleres, or teams, compete to build the highest, most unique tower of people.
In the Ring The 2010 competition took place on Oct. 3. Some of the towers were built in the city's bullring. Others were constructed in the streets.
On the Way Up The colles use a variety of strategies and techniques. Some of them, like the Xiquets de Tarragona, use children for the uppermost tiers, presumably because they weigh less.
Watch It!The construction requires a precise choreography, as the participants must coordinate their ascent to ensure that the balance of the structure remains sound.
Way Up
The structures can employ as many as 200 people.
