Some weeks ago, with the usual wild bunch (César, Lapin, Sagar, Víctor and Javier de Blas who had stopped for a few days in Barcelona on his long trip throughout the Mediterranean coast), I had the opportunity to attend a couple of the indoor rehearsals of the Castellers de Sants (Sants is a neighborhood of Barcelona). They are one of the most famous collas (teams) of castellers in all Catalonia. This are not my first castells live but in this occasion I could see everything from different high levels and I could appreciate the intricate way they construct the basis, the different figures and roles, and the complex organization and hierarchy of the colla.
At some times I had to stop drawing: seeing l'enxaneta (the 6-8 y.o. child that ends the castell) scaling a human tower till the 9th "floor" is really hypnotizing. I felt as pushing with my eyes to help all that remain standing.
Here are all them building a 9 floor castle.
