Festivities of Silla Activity · Silla, L'Horta Sud, Valencia Image of Silla, not of the place itself. Silla's patronal festivities reach their main day on the 6th of August, the feast of the Santíssim Crist, with the Dansa dels Porrots -an old warrior dance performed by groups of eight dancers- and the singing of the Carxofa, a scenic contraption shaped like a palm tree from which a child singer emerges.
