Cross the dock to enter the exclusive Puerto Madero neighbourhood. First visit the Museum of Reproductions and Comparative Sculpture (Av. España 1701). Here you'll find replicas of important works of sculpture such as Moses and Venus de Milo. Then, going north along Av. España, take a look at another monumental sculpture, Las Nereidas (Av. Tristán Achával Rodríguez 1550), which was created by Lola Mora, considered South America's first female sculptor.
The Tucuman-born artist presented her work in the Plaza de Mayo in 1903, but the city's aristocracy disapproved of displaying the figures of naked women so close to the cathedral, and the sculpture was moved 15 years later to its current location. The piece has a Renaissance style and is coated in Carrara marble.
Directly opposite is the entrance to the Costanera Sur Ecological Reserve. This immense natural park is a haven for native wildlife, including 250 species of birds, amphibians, reptiles and mammals. Although it seems incredible, the park is just metres from the city's downtown financial district. The site was at one time a popular bathing area.
A tour of the reserve will lead you to another exit located at the intersection of Int. Hernán Giralt and Mariquita Sánchez de Thompson. Skirt around the dock until you reach the ship moored there: the A.R.A “Uruguay” museum ship, which was built in 1874 for the Argentine Navy. The ship once took part in an operation to rescue Otto Nordenskjold's scientific mission. It's now open every day.
You'll find another museum ship in the next dock: the Sarmiento Frigate was used a schooling ship for the Argentine Navy for 39 years and travelled the equivalent of 42 laps of the globe.
