This paper describes and analyzes the phenomenon of new festivities, those which were created or reinvented in our days by local communities under laic premises, but despite of not being driven by religious beliefs, they still display formal analogies with religious festivities. Neo-festivities, similarly to religious feasts, develop a ruled ritual and invent their own narration which they convert into the ground of their own discourse and their message. This article's case study is the Festa da Istoria (Ribadavia, Galicia), an event which intends to relive the Middle Ages, a period considered to be this town's moment of highest splendour.
