Rosario

Rosario, officially the Autonomous City of Rosario, is a city in central Argentina, in the south of the province of Santa Fe. Located 300 km (186 mi) northwest of Buenos Aires on the west bank of the Paraná River, it is the country's third-most populous city after Buenos Aires and Córdoba. With a growing and important metropolitan area, Greater Rosario has an estimated population of 1,750,000 as of 2020. One of its main attractions includes the neoclassical, Art Nouveau, and Art Deco architecture that has been preserved in hundreds of residences, houses and public buildings. The city is also famous for being the birthplace of Argentine footballer Lionel Messi.

Rosario is the head city of the Rosario Department and is located at the heart of the major industrial corridor in Argentina. The city is a major railroad terminal and the shipping center for north-eastern Argentina. Ships reach the city via the Paraná River, which allows the existence of a 10-metre-deep (34 ft) port. The Port of Rosario is subject to silting and must be dredged periodically. Exports include wheat, flour, hay, linseed and other vegetable oils, corn, sugar, lumber, meat, hides, and wool. Manufactured goods include flour, sugar, meat products, and other foodstuffs. The Rosario-Victoria Bridge, opened in 2004, spans the Paraná River, connecting Rosario with the city of Victoria, across the Paraná Delta. The city plays a critical role in agricultural commerce, and thus finds itself at the center of a continuing debate over taxes levied on big-ticket agricultural goods such as soy.

Along with Paraná, Rosario is one of the few Argentine cities that cannot point to a particular individual as its founder. The city's patron is the "Virgin of the Rosary", whose feast day is 7 October.
