La Diada de les Neus is the main casteller event of the Vilanova i la Geltrú summer festival. Held each year at the end of July or the beginning of August, it brings together the local group, the Bordegassos de Vilanova, alongside other leading teams. In the Plaça de la Vila, the colles attempt constructions of the highest complexity. It stands out as one of the most notable dates in the calendar and a point of reference in the casteller world and Catalan culture.
