My image of the Catalan Human Castles has just been published in the July 2011 edition of National Geographic Magazine.

The tradition, which dates back to end of the 18th century in Catalonia in Spain has been included by UNESCO in the list of intangible cultural heritage of humanity.
The towers are built by “castellers” who belong to groups called “colles” and intricate techniques are used to complete the highest and most complex castle. There are three parts to a castell and each varies in width and height. Some reach eight storeys high and even 10 storeys has been achieved. A young child normally climbs the whole tower and salutes the crowds from the top. Sometimes the towers collapse and serious injuries, even death, can result.
The amazing feat requires strength, teamwork, concentration and discipline. The motto of the castellers is strength, balance, courage and wisdom.
