Built by Jesuits in the late 1600s, the tunnels were initially intended to connect important religious and governmental buildings, including churches like San Ignacio and strategic sites like the Cabildo. The tunnels were designed for practical purposes, but their exact use is still debated. Were they escape routes, secret passages for contraband, or simply a means to move goods safely?

Another layer of intrigue surrounds tunnels beneath the Casa Rosada, some of which were used for transportation purposes in the early 20th century. These tunnels stretch beneath Avenida Rivadavia, once part of the Ferrocarril Oeste project, linking the port with the heart of the city. Legends also tell of hidden passageways connecting the Casa Rosada with the Ministerio de Economía, creating an air of mystery about their true purpose.

Today, visitors can explore parts of these tunnels during guided tours, uncovering centuries-old secrets and learning about Buenos Aires’ fascinating past. Whether built for defense, escape, or trade, the tunnels continue to add an air of mystery to this vibrant city.

The Hidden Rivers of Buenos Aires

Beneath the vibrant neighborhoods of Buenos Aires, rivers like the Río Matanza-Riachuelo and Río de la Plata continue to flow, though largely hidden from view. These underground rivers have played a crucial role in the city’s water management system for centuries, helping to control floods and supply water during dry periods.

Subterranean waterways such as the Río de la Plata, which flows all the way from the South Atlantic, have shaped the urban planning of Buenos Aires. In some neighborhoods, remnants of these rivers can still be found winding beneath the surface. While many have been channeled or redirected, they remain an integral part of the city’s water infrastructure.

  • Tip for Urban Explorers: If you want to see where these rivers once surfaced, take a guided tour through the historic districts like San Telmo, where underground streams flow through ancient aqueducts.

One of the most fascinating parts of Buenos Aires’ underground world is the network of hidden tunnels, some of which date back to the early colonial era. The most famous of these is El Zanjón de Granados, a series of tunnels located in the San Telmo neighborhood.

Originally built to divert rivers and rainwater, these tunnels have also been used for defense and escape during Buenos Aires’ colonial past. Today, they offer an intriguing journey through time, allowing visitors to explore a hidden layer of the city’s history.

  • El Zanjón de Granados: Restored and opened to the public, these tunnels provide a unique view of Buenos Aires’ early infrastructure, from the colonial period to modern times.

The Role of Subterranean Rivers in Urban Planning

While Buenos Aires has grown into a sprawling metropolis, the subterranean rivers and tunnels beneath the city remain a vital part of its infrastructure. These hidden waterways play a key role in regulating the flow of water, preventing floods, and supplying groundwater.

Historically, Buenos Aires depended on these rivers for its water supply, and although modern plumbing has largely replaced them, they still provide natural drainage for the city. The subterranean network also supports sustainability efforts as a backup during droughts.

Sustainability and Conservation of Hidden Rivers

As Buenos Aires continues to expand, maintaining and preserving these underground rivers and tunnels is a growing concern. Efforts are being made to ensure that pollution and urban runoff don’t contaminate the groundwater flowing through these hidden waterways.

Several conservation initiatives are in place to preserve these historical structures. Community engagement has played an important role, with local organizations offering educational programs and workshops to raise awareness of the importance of preserving Buenos Aires’ subterranean world.
