El Zanjón de Granados, Archaeological site and tourist attraction in San Telmo, Argentina.
The underground complex features a network of brick tunnels, cisterns, and archways beneath a restored 1830s Italian-style mansion in Buenos Aires.
During the 1980s renovation of the property, workers uncovered foundations of an 18th-century colonial house and water management systems from early Buenos Aires.
The site presents four centuries of urban development through preserved architectural elements, from colonial structures to 20th-century residential buildings.
Guided tours are available in multiple languages, with special rates for seniors, students, and residents of Argentina at Defensa 755.
The excavation revealed an original stream called Tercero del Sur that flowed from Plaza Constitución towards Río de la Plata through Pasaje San Lorenzo.

Buenos Aires reveals a patrimonial wealth that goes beyond the usual circuits. This collection gathers places that tell the story of the Argentine capital through its architecture, green spaces, and cultural institutions. From the XVIIIth-century tunnel network of El Zanjón de Granados to the 22 stories of Palacio Barolo, these sites reflect the city's urban evolution. The itinerary includes diverse sites such as Palermo's Japanese Garden with its ponds and pavilions, the Museo de Arte Español Enrique Larreta showcasing works from the Middle Ages to the 20th century, and the moving Floralis Genérica sculpture whose petals open at sunrise. Neighborhoods like San Telmo, Barracas, and Colegiales offer architectural discoveries such as 19th-century passages, facades decorated with mosaics on Calle Lanín, and the Mercado de las Pulgas filled with Argentine antiques. These locations allow exploring Buenos Aires beyond postcards and observe how the city has preserved its history while growing. Each site provides a different perspective on porteña culture, from Carlos Gardel’s tango to European and Asian influences shaping the city’s identity.
