Of pre-Hispanic origin and previously known as the Espinosa Pool, this space supplied water to the estates south of Chapultepec Hill, such as La Condesa.

In the 19th century, a renowned bathhouse complex was built in front of this water reservoir: the Casa Baños de Chapultepec, owned by José Amor y Escandón. These baths were inaugurated on April 1, 1870, and closed in August 1881.

Eventually, the Escandón family sold the property to the city council, which demolished the baths and integrated the land into Chapultepec Forest, leaving only the pre-Hispanic water container standing. By 1910, the area was renovated for the Centennial of Mexico’s Independence and renamed “Moctezuma’s Baths.”
