President Domingo Sarmiento was responsible for the laying out of the Parque Tres de Febrero in land previously owned by Juan Manuel de Rosas. The project was begun in 1874; the park was opened on November 11, 1875, and included a small section dedicated for animals. This area was owned by the Federal Government until 1888 when it was transferred to the City of Buenos Aires. In that year, Mayor Antonio Crespo created the Buenos Aires Zoo, and separated it from the rest of the park.
