There are quite a number of festivals and traditions in Catalonia (Spain). While most are of ancient origin, certain traditions are of relatively recent introduction. There are also some that are common to the whole Catalan society, but others are relevant only to a particular location. Generally, locals welcome outsiders to share with them in their celebration. Festivals and celebrations The correfocs, in which "devils" play with fire close the onlookers, is one of the most striking of the Catalan festive events.
