 The festival of Saint Roch (Sand’Rocc) is unique to Irsina.Every year on 15 August (a national holiday known as 'Ferragosto'), women in the old town of Irsina prepare small altars in their basements, garages and cellars, in honour of the Saint from Montpellier, to be visited from the evening of the 15th until dawn of 17 August.For two nights locals stay awake, singing nursery rhymes, in dialect, that recount of the life and miracles of Saint Roch.
