Rosario is a Uruguayan city located in the department of Colonia.
It was founded in 1785 by the Spanish governor José Joaquín de Viana. During colonial times, the city became an important river port due to its strategic location at the mouth of the Rosario River in the Uruguay River. During the Great War (1839-1852), Rosario was the scene of important confrontations between the political parties that were fighting for control of the country.
In 1865, the city was bombarded by the Brazilian fleet during the Paraguayan War. Despite this, Rosario continued its development and became an important commercial and transportation center in the region.
Currently, the city has an important tourist activity due to its rich history and cultural attractions, such as the Regional Historical Museum, the Matriz Church and the monument to General José Gervasio Artigas, considered the father of the Uruguayan nation.
