A memorial park on the northern riverbank, opened in 1999, dedicated to the 30,000 people who disappeared during Argentina's military dictatorship of 1976–83. The central monument — a deep zigzagging cut through the ground, lined with the names of the victims — was designed to be visible only from below, forcing visitors to descend into it rather than observe from above.
The park also functions as an outdoor sculpture museum, with major Argentine and international works installed throughout the grounds. The sculptures address themes of memory, violence, and loss without being didactic. The setting — open water on one side, the city skyline behind — adds to the weight of the place. Allow an hour; it is not a quick visit.
