Nossa Senhora do Rosário, or Our Lady of the Rosary, is a title given to the Virgin Mary in the Catholic Church. This title emphasizes her role in the prayer of the Rosary, a form of meditation that involves the repetition of prayers and the contemplation of significant events in the lives of Jesus Christ and Mary. The feast day of Nossa Senhora do Rosário is celebrated on October 7. The devotion to Nossa Senhora do Rosário is particularly strong in countries like Brazil and Portugal, where she is often depicted in art and religious iconography. Many churches and shrines are dedicated to her, reflecting her importance in the spiritual lives of the faithful. The Rosary itself is a popular prayer tool among Catholics, symbolizing peace and reflection.
