Parque Rodó Parque Rodó is both a barrio (neighborhood) of Montevideo and a park which lies mostly outside the limits of the neighborhood itself and belongs to Punta Carretas. The name "Rodó" commemorates José Enrique Rodó, an important Uruguayan writer whose monument is in the southern side of the main park. The park was conceived as a French-style city park.
