Our Lady of the Rosary of San Nicolás

Our Lady of the Rosary of San Nicolás is, in Catholicism, a title of veneration of the Virgin Mary associated with reported private revelations to Gladys Quiroga de Motta, a middle-aged housewife, beginning in 1983, in the city of San Nicolás de los Arroyos, Argentina. Gladys said that she was tasked with promoting this devotion to the Mother of God under this title, with an emphasis on key passages in the Bible and a particular mystical stellar symbolism.

The apparitions have continued almost every day since 1983 and have been approved by the Catholic Church. Messages from 1983 to 1990 have been officially approved and published, and miracles, conversions and healings are said to occur in the Sanctuary of Our Lady of the Rosary of San Nicolás in Buenos Aires, Argentina. Under the title María Del Rosario de San Nicolas, de Motta stated that the Virgin Mary called Catholics to pray one hour per day, to receive the Eucharist daily, to repentance and conversion.

The pilgrimage site, named in honor of Our Lady of the Rosary of San Nicolás erected in San Nicolás de los Arroyos, is one of the most important in Argentina.
