The Monumental Fountain of Las Nereidas is a sculpture of approximately 6 meters high and 13 meters wide, built with Carrara marble specially arrived from Italy. It was made by the artist Dolores “Lola” Mora, one of the first sculptors of Argentina and Latin America: a mysterious artist, extremely talented and very controversial for her time.

The work was inaugurated on May 21, 1903 and, for 15 years, it remained in the same place: the current intersection of Perón streets and Leandro Alem avenue. It was to be located where the Pyramid of May, but the decision was interrupted when a sector of society criticized the nude scenes, considered indecent at the time.

In 1918, with the help of the artist herself, the Fuente de las Nereidas was moved to a more remote place: the Costanera Sur, in the current neighborhood of Puerto Madero. The conservatives considered the move of the work as a victory, since in this way it was far from the center of Buenos Aires and from everyone's gaze. Today, after the multiple transformations of the City, that geographic point is one of the entrances to the Buenos Aires Ecological Reserve.

The fountain represents the birth of the Goddess Venus, assisted and supported by two creatures that give the work its name: the Nereids. These Nymphs of the ocean, daughters of Nereus, the god of the sea, represent, in Greek mythology - in addition to beauty and seduction - a certain compassion for sailors and humanity. The fountain is completed by three newts mounted on their horses, emerging from the water.

In 1997 the work was declared an Asset of Historical Interest by presidential decree.
