Reserva Ecológica Costanera Sur

Av. Dr. Tristán Achával Rodríguez 1550, Cdad. Autónoma de Buenos Aires

Riverside wetland grown wild on landfilled rubble, with trails for jogging, cycling and birdwatching.

This guide to the Reserva Ecológica Costanera Sur in Buenos Aires traces how a 1977 highway-building spree under Argentina's military government left thousands of tons of rubble dumped along the riverbank for a planned neighborhood that never got built. You'll hear how the project collapsed with the dictatorship by 1983, and how the city spent years debating what to do with a wasteland nobody had asked for. Listen for what the 1986 city council vote finally decided, and look down at the path itself for what's still surfacing after nearly fifty years.
