During colonial times, the Spanish brought their religious catholic fervor to Nicaragua, which was imposed and then strongly embraced by the indigenous peoples, with a mystical character and intense piety. This is the origin of the popular religious Nicaraguan festivities of today. ‘La Purísima’ is celebrated in primarily in December and is one of the most widespread celebrations in the country.

The festivities begin on November 28th when the Virgin's image is taken from the church so that she may visit the different barrios (neighborhoods) of the town.

From November 29th until December 13th, the procession of the Virgin goes to different barrios on peoples' shoulders, or on the back of pick up trucks. The procession is accompanied by decorations, music and bombas (firecrackers). Families and barrios decorate alters and floats in honor of various themes related to the Virgin Mary.

During the period of Purisma, a mass is celebrated every morning. These masses are the starting point for the day's procession to a specific barrio. A rosary is read at the barrio in early evening after which chicha, a traditional drink made from maiz, and sweets are distributed to the people. A few hours later the procession of the Virgin returns to the Church.
