Located in the ancient San Telmo, Zanjon de Granados (Granados's Gorge) is famous for the historical tunnels hidden inside.

Buenos Aires was founded in 1580 and during most of our past, the population was concentrated in the South (PLaza de Mayo and San Telmo).

Excavations in the 1830 old mansion led to the uncovering of the ancient Zanjón (gorge) which extended over the whole length of the square. Belonging to a wealthy family, the property was turned into a tenement by 1890.

After more than 20 years of restoration, it is now part of "El Zanjón - Idea Site" that includes three buildings and is internationally recognized as an archaeological site of the city.

At present, El Zanjón exhibits a unique urban archeology project and a glimpse into the past of Buenos Aires, In here, you will know about those inhabitants of the XVIII and XIX Century, about their uses, and firstly, how they get and treat water.
