Our Lady Of Castelbruedo
It is related that every year on the day of the Annunciation, three lights of a blue color were seen, shining through the glass windows of the church at Olion in Catalonia.
Here Our Lady is venerated under the title of Our Lady of Castelbruedo. The lamps and the wax candles were likewise lighted by invisible hands, and all disappeared three days after the feast, on the twenty-eighth of March. Despite all investigation, the lights and their extinguishing could not be accounted for; but it was universally taken for granted that all this was to honor our Lady’s great feast.
