Día de la Imaculada (the Immaculate Conception) - this national
religious holiday celebrates the Virgin's immaculate conception.
This fiesta has been observed since the 7th century in the
Orient, since the 9th century in Ireland and in Spain since the 11th
century. Of the country's many religious observances, this particular
one is of key importance for its relevance in the Christian faith.
Pious people attend a celebratory mass and generally spend it as they would a Sunday.
