A religious celebration with a very important civic component, held every 14th of January. It stems from an event that took place over 200 years ago. Between 1770 and 1773, Ejea suffered an epidemic outbreak which caused an alarming increase in mortality, spreading fear among the people. Faced with this situation and the inefficiency of the healthcare resources, the General Council asked the Church Chapter to have the image of the Immaculate Conception in a religious procession. On January 14, 1773, that procession took place and, short after that, the epidemic outbreak diminished and was virtually eradicated. It was then when the ejean people, to express gratitude to the Lady, established the Voto a la Purísima, that is still celebrated every January 14.
