context_page_description: San Nicolás de los Arroyos is a city in the province of Buenos Aires, Argentina, on the western shore of the Paraná River, 61 km from Rosario. It has about 133,000 inhabitants. It is the administrative seat of the partido of the same name. It is sometimes called Ciudad de María due to a series of Marian apparitions that led to the erection of the Sanctuary in honor of Our Lady of the Rosary of San Nicolás that began during the 1980s and were approved by Bishop Cardelli of the diocese as "worthy of belief" in 2016.
context_section_description: San Nicolás de los Arroyos was founded on 14 April 1748 by Rafael de Aguiar, who gave it its name to honour Saint Nicholas of Bari, now patron of the city.
  The closeness to the border between Buenos Aires and two other large provinces made the city a natural stage for the struggle between federalist and Unitarians forces in mid-19th century. The agreement between thirteen provinces on 31 May 1852, which ratified the Federal Pact and called for a Constitutional Assembly sponsored by Justo José de Urquiza, was signed in this town, and became known as Acuerdo de San Nicolás de los Arroyos.
