Parque Batlle is named in honour of José Batlle y Ordóñez, President of Uruguay from 1911 to 1915. The park was originally proposed by an Act of March 1907, which also projected wide boulevards and avenues. French landscape architect, Carlos Thays, began the plantings in 1911. In 1918, the park was named Parque de los Aliados, following the victory of the Allies of World War I. On 5 May 1930, after significant expansion, it was again renamed as Parque Batlle y Ordóñez, in memory of the prominent politician and president, who had died in 1929. The park was designated a National Historic Monument Park in 1975. As of 2010[update], the park covers an area of 60 hectares (150 acres) and is considered the "lung" of the Montevideo city due to the large variety of trees planted here.
