San Nicolás de los Arroyos is located on the banks of the Paraná River in northern Buenos Aires Province, serving as a city of immense historical and economic weight. Founded in 1748 by Rafael de Aguiar, it was the site of the 1852 San Nicolás Agreement, which paved the way for the Argentine Constitution. Today, the city stands as a major industrial powerhouse, anchored by the Siderar steel plant, one of the largest in Latin America. Beyond industry, San Nicolás has emerged as a significant religious pilgrimage site following the reported Marian apparitions in 1983, with millions visiting the Sanctuary of Our Lady of the Rosary each year. The city's river port is a critical node for exporting agricultural and industrial products. Its urban landscape is enriched by cultural landmarks like the Italian-style Municipal Theater and the scenic waterfront promenade along the Paraná.
