Overview

• Parishes and shrines mark October 7 with Masses, processions and communal recitation of the Rosary, with strong participation reported across Argentina.
• The devotion is traditionally traced to a circa‑1208 apparition of the Virgin Mary to Saint Dominic, who promoted the Rosary as a meditative prayer on Christ’s mysteries.
• Pope Pius V established the feast after the 1571 Battle of Lepanto, Gregory XIII adopted the title Our Lady of the Rosary, and Pius X fixed October 7 as the permanent date.
• October is observed as the Month of the Rosary, following a nine‑day novena that typically runs from September 28 to October 6.
• Prominent sites of devotion include the shrine at Pompeii in Italy and Argentina’s San Nicolás, with patronages noted in cities such as Rosario, Paraná, Suipacha and Alberti.
