Pereyra Iraola Provincial Park[1] (Spanish: Parque Provincial Pereyra Iraola) is a Provincial Park and is the largest urban park located in the province of Buenos Aires, Argentina.[2] It is the richest center of biodiversity in the province.[3]
The land used to belong to the Pereyra Iraola family, who acquired it from Juana Rita Pinto. In 1949, the family was expropriated by the government headed by General Juan Domingo Peron to build a community park which was opened a year later. The park measures 10,246 hectares and is located between the cities of Berazategui, Ensenada, Florencio Varela and La Plata.
During the second presidency of General Peron, the area encompassing the current park and the train station that links the Buenos Aires train station Constitución with the La Plata train station, were called Derechos de la Ancianidad (trans. "Rights of the Elderly").
