San Pedro, Buenos Aires
The historic Battle of Vuelta de Obligado took place on the town's Paraná River shores on November 20, 1845. The city is home to a sizable Italian Argentine community, who established the local "Sociedad Italiana de Unión y Benevolencia", a charitable organization, in 1873. San Pedro was officially designated as a city by the Provincial Legislature on July 25, 1907. A former Querandí settlement, a vestige of the area's original inhabitants, was unearthed nearby by archaeologists in 1965. The nation's largest newsprint maker, Papel Prensa, established its principal facility in San Pedro in 1978.
