I can’t imagine the bravery it must take to be the person at the very top of the castell.
… who is more than likely a very young child. The base of the tower is made up of burly dudes, but the higher up you get, the smaller and lighter the castellers have to be. There’s usually a “skinny teenage girl” layer somewhere toward the top, but the enxaneta (“rider”) who climbs to the very top can be as young as six or seven.
As well as static castells, there’s a pilar caminant (“walking pillar”) which actually moves; the pilar has just one person at each level (presumably you could have a castell or torre caminant but I never saw it done). One that I saw collapsed twice; the first time, they rebuilt the pilar and the tiny enxaneta got right back up; the second time, everyone decided that enough was enough, and the rather tearful child got big hugs from all the women present until he felt better.
I have some pictures of castellers where you can see how really tiny some of the kids involved are. (This was the pilar caminant, complete with its enxaneta).
