castle's origin     We most loking for humain constructions' origin in an ancient dance called "baile de valencianos" which finished with a humain construction formed by one or two persons at the base, named a pillar or a tower respectively. These constructions are called "torreta".      Humain constructions has became the whole population expression. In these structure we can find people from 5 or 6 years old to the eldest ones since in order to achieve the success we need the all people participation, this one of the "castellers" and public also. The public helps to give pressure around the "pinya" (people who maintain stable the construction's structure and reduce the risk in case of downfall.      People's groups doing these constructions get the name of the city where they are living in and you can identificate them by their shirt's colour and constructions' variety.      We define every construction depending on the amount of persons placed on every floor and its height. The aim is always the same: "enxaneta" has to greet from the highest part of the castle. At this moment the construction is considered valid; afterwards the structure is dismounted floor by floor.
