The first public official to rally to this need was the Minister of Education of the Province of Tucumán, Alberto León Soldati, who in 1898 proposed the creation of an extensive green space such as those under development in Buenos Aires, Rosario and Córdoba, the nation's three largest cities.
Lake San Miguel (named in honor of the city's patron saint) and a rose garden were created to the south of the historic residence, common denominators to most of Thays' public parks.
The founder and first President of the University of Tucumán, Doctor Juan Bautista Terán, purchased 20 cast iron, glazed sculptures in France for the park and the planned Liberal Arts campus therein, opened in 1914.
Later additions included a campground, a topiary sun dial, the Tucumán Lawn Tennis Club, the Municipal Cultural Center and Sports Complex, the University's Odontology and Physics campuses and the Nasif Estéfano Speedway.
The parkland south of Lake San Miguel was gradually replaced facilities such as the Tucumán Hippodrome and a public orphanage built by the Eva Perón Foundation (opened in person by the first lady in 1950).
