First documented in 1712, the tradition of building castells originated in the southern Catalan town of Valls. Groups of locals constructing human towers started to compete with each other, the beginning of a whole new kind of sporting event.
A castell consists of adding layers from the bottom, step by step, and takes a great deal of practice, skill and strength. Until the 1980s, it was known as a male-only discipline; the inclusion of women allowed for the building of lighter and stronger constructions. In 2010, UNESCO recognized Catalonia's human towers as an Intangible Cultural Heritage of Humanity.

The pinya also acts as a “safety net” if the tower structure collapses, cushioning falls.
