The 4 of 9 with single base is an extra range tower composed by nine levels and four people per level with a single base. It is one of the most difficult and fragile towers due to the number of levels without reinforcements. It is considered the “Total Castell”.
The first 3 of ten with triple base was crowned by the Castellers de Vilafranca on November 15th of 1998 at the Plaça de la Vila of Vilafranca del Penedès.
One week later, in their XX feast, the group Minyons de Terrassa completed this tower for first time in the history of castells, at the Plaça Vella of Terrassa.
