Payubre
Payubre is the old name of the country around Mercedes, near the stream of the same name in the plains of Corrientes. In the late eighteenth century cattle estates appeared between the Payubre Grande and neighbouring watercourses. Settlers near the stream petitioned for a town in 1825. A church was begun in 1832 and dedicated to Our Lady of Mercy in 1835, when the growing settlement acquired the name Mercedes.
