Unity personified, are these ¨Castellers¨, or human towers. The Art of Castellers, is as much a part of the Catalan tradition and psyche as Antonio Gaudi´s architecture is to Barcelona. Performed throughout the northeastern province of Spain during festivals and as friendly competitions, the Castellers are the result of years of practice in formation and safety. The participants, both women and men, join young and stay on to become guides, mentors and ultimately teachers of their younger peers that follow. They proudly pass on their long cherished wisdom to the next generation of Castellers, literally by lending their arms and limbs in the creation of these unique human towers.
