Inaugurated in 2007, though still nowhere near completion, the Parque de la Memoria combines a number of original sculptures and other works of art with a memorial wall listing the names of the military dictatorship's victims. Set on the banks of the Rio de la Plata - particularly appropriate, given that victims of the regime were frequently found washed up on shore - the Park will also ultimately serve as a research center, supporting investigations into the dictatorship's abuses. Our guide, Tomas Tercero, led us by the major works currently on display, describing the symbolism at work in each.

This untitled work by Argentine Roberto Aizenberg focuses on three individuals. Presented only in outline, the implication is one of absence - the people are missing and only memories remain. The three shapes are intended to represent the most common victims - men, women, and pregnant women specifically.

"Victory," by American William Tucker, uses its own incompleteness and awkward design to represent the valor and resilience of those who fought the dictatorship.

Created by American sculptor Dennis Oppenheim, "Monument to Escape" turns three prison cells on their side, turning the very concept of imprisonment on its head as a symbol of liberation.

Comprised of 25 rectangular prisms, this fragmented work by Argentine Nicolas Guagnini changes its appearance as the viewer moves by it. From straight on, the portrait of Guagnini's father is clearly visible, nearly whole. However, walk far enough and the image splinters, it disappears, as did Guagnini's father and the other "30,000."

Not a work of art, but rather a lasting reminder of the many victims of the military government. The 30,000 are all present.

This project, organized by a group of Argentine art teachers, actually started outside of the park. The idea was to use institutional symbols to denounce illegitimate institutions by exposing their crimes. Each street sign, sometimes slightly modified, is accompanied by a small board describing the intent.
