San Nicolás de los Arroyos (usually shortened toSan Nicolás) is a city in theprovince ofBuenos Aires, Argentina, on the western shore of theParaná River, 61 km (38 mi) fromRosario. It has about 133,000 inhabitants (2010census[INDEC]). It is the administrative seat of thepartido of the same name. It is sometimes calledCiudad de María (City of Mary) due to a series of Marian apparitions that led to the erection of the Sanctuary in honor ofOur Lady of the Rosary of San Nicolás that began during the 1980s and were approved by Bishop Cardelli of thediocese as "worthy of belief" in 2016.[1]
San Nicolás de los Arroyos was founded on April 14, 1748 by Rafael de Aguiar, who gave it its name to honorSaint 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 betweenfederalist andUnitarians forces in mid-19th century. The agreement between thirteen provinces on May 31, 1852, which ratified theFederal Pact and called for aConstitutional Assembly sponsored byJusto José de Urquiza, was signed in this town, and became known asAcuerdo de San Nicolás de los Arroyos.
The city is located in the north-east of the province of Buenos Aires, 240 km fromBuenos Aires City, within the so-calledIndustrial Corridor that goes fromGreater Rosario toLa Plata. Its limits are: to the west,Pergamino; to the south,Ramallo; to the east, with the Paraná River, which separates it from the province ofEntre Ríos; and to the north, with theArroyo del Medio, a small river that separates it from the province ofSanta Fe.
Its main accesses are in the north–south axis: theRosario-Buenos Aires Highway, and theNuevo Central Argentino railroad.
San Nicolás hasan important port on the Paraná, able to service large cargo ships. The railway system has passenger and cargo stations, the latter reaching up to the port.

The city has 43 kindergarten institutions, 58 schools of Elementary Education, 28 of High-school level (both public and private), 26 schools for adults and a large number of tertiary studies institutes.It is also home of the San Nicolás Regional Faculty, a branch of theNational Technological University (UTN).
There are a variety cultural institutions in the city, though the most important one is perhaps theRafael de Aguiar Municipal Theatre, founded on August 10, 1908, and designed as a smaller model of theTeatro Colón in Buenos Aires.
Among the many libraries in the city, the oldest and largest is theRafael de Aguiar Popular Library, founded in 1947 by Juana Couretot de Guella.
