Strength! Balance! Bravery! The castellera festival begins and all the castellers strive to be the first among the groups building human castles in front of the crowds of spectators. The group that builds and ascends their castells first will receive more applause, but be careful. One slip and the castell will make Ilenya, and the entire tower comes tumbling down! Fortunately, the coordinator is always careful to give precise directions so that the castell can be successfully completed. The gralles are playing! Tercos amunt!
