June 16th is the Saints Day of Sant Quirze and Santa Julita, who were son and mother respectively. They are the patron saints of Calella in El Maresme and the reason for the town's Festa Major.
Sant Quirze and Santa Julita lived in Tars and according to legend were martyred in AD 304.
Although there is virtually no documentation concerning their lives and deeds and they are probably the result of pious invention, Sant Quirze and Santa Julita are venerated through the Christian world.
Sant Quirze is a common town name in Catalonia and this probably due to the legend that the Frankish King Charlemagne had a dream that he was being attacked by a wild bear and was saved when a child, apparently Sant Quirze, appeared asking him for clothes.
If you're familiar with Catalan history, you will know that it was Charlemagne and his heirs who reconquered Catalonia from the Muslims in the 8th and 9th centuries.
