Directing Urban Parks in Buenos Aires

In 1891, Thays assumed the role of Director of Parks and Walkways in Buenos Aires. During a period of rapid demographic expansion fueled by international immigration, he exerted significant control over the city's green spaces. His interventions included the design of parks such as Centenario, Lezama, and Patricios, as well as the redesign of public squares like Plaza Constitución and Plaza Congreso. He frequently incorporated elements of his French training into these urban layouts.

The Botanical Garden and National Parks

Thays lobbied for the establishment of the Buenos Aires Botanical Garden, which occupies eight hectares and was completed in 1898. He organized the facility by continent and emphasized the inclusion of native Argentinian species. His advocacy extended to the creation of the national park system, specifically regarding the Iguazú Falls. In 1912, he submitted a technical report to the Minister of Agriculture, Adolfo Mujica, outlining the environmental and tourism potential of the region.

Regional Projects and Legacy

Outside the capital, his portfolio included the Parque de la Independencia in Rosario, Parque 9 de Julio in San Miguel de Tucumán, and Parque Urquiza in Parana. He also executed projects in Montevideo, Uruguay, including the design of Plaza Cagancha and Plaza Independencia. A recipient of the Knight of the Legion of Honour in 1911, he died in 1934 and is buried at La Chacarita Cemetery.
