In the first week of December, Catholics in Nicaragua gather on evenings to pray novenas in preparation for la gritería ("the shout"), a Nicaraguan festival which originated in the early 18th century, held in honor of the Immaculate Conception of Mary, also nicknamed la Purísima.
This holiday celebration holds special significance in the city of León, where it originated.
Here, Fieldwork Archivist Claudio Alexander Urbina joins his parish in the Laborío neighborhood of León in singing a Purísima hymn for one of these novenas.
