French immigration has left a significant mark on Argentina, with a notable influence on the arts, culture, science and society of the country. Many emblematic buildings in cities like Buenos Aires, Rosario, and Córdoba were built following French Beaux Arts and neoclassical styles, such as the Argentine National Congress, the Metropolitan Cathedral, or the Central Bank building. In particular, landscape architect Carlos Thays, in his position as 1891 Director of Parks and Walkways, is largely responsible for planting thousands of trees, creating the Buenos Aires Botanical Garden and giving the city many of its parks and plazas that are sometimes compared to similar designs in Paris.
