The Uruguay Department produces 47% of the nation's poultry, and Concepción del Uruguay together with Gualeguay and Colón make up 85% of Argentine chicken exports.
It passes by the cities of Villaguay, Rosario del Tala, and Gualeguay, and finally empties into the Río Paraná Ibicuy, a distributary of the Paraná River in the Paraná Delta.
Gualeguay was founded on March 20, 1783, by a military surveyor, Tomás de Rocamora, sent by the Viceroy of the Río de la Plata, Juan José de Vértiz y Salcedo.
There are collections of his art in Buenos Aires, Curitiba, Genoa, Gualeguay, Montecatini Terme and Piacenza.
