"Exploring an urban archaeological site at El Zanjón de Granados Touring this one-of-a-kind urban villa and archaeological site allows a unique insight into the city's history. The beautifully restored urban mansion was once the residence of a wealthy Spanish family; they fled for higher ground when yellow fever struck San Telmo, and the abandoned building later served as tenement housing for countless immigrant families. When a new buyer purchased the property in 1985, he discovered layers of historical objects in the subterranean tunnels. Today, knowledgeable local guides take small groups through the grand villa and its underground maze, pointing out the old water cistern and display cases filled with antique children's toys, old hairbrushes and beautifully painted dishes, reminders of an era gone by."

We visited on a Tuesday afternoon (4pm) tour. The guide, Martin, was very well prepared, friendly and accommodating. The history of the house and tunnels is fascinating.

Excellent museum! They operate only on private tours so ensure you show at the right time based on your language. The scale of the mansion and the ruins makes you feel like you’re in Athens or in Rome. Highly recommend and not crowded.

Wonderful tour with Rocio. Loved her passion of story telling about the origin of the city and the culture background. It made a richer experience of BA for me like a time walking to the past in 19th century.

This as much a museum as a HISTORICAL RECONSTRUCTION of a EXCAVATED OLD MANSION (turned conventillo) from old Buenos Aires. *** It’s an illustration of the evolution of neighborhoods/communities: from large mansions of the rich, to their abandonment, to their re-habitation and conversion to communal dwellings of the poor. From the colonization viewpoint, the mansion shows the startling strength of Bricks and Adobe in the construction of colonial dwellings! From the social viewpoint, illustrates the wealth of Spanish colonial aristocrats…. AND implicitly, the poverty of those who later domiciled in the rooms on the mansion (called Conventillos) sharing kitchens and latrine, when owners abandoned their mansions to escape the local epidemic. The story of the “tunnels (Zanjón)” is more fascinating. These tunnels were, in effect city drains and/or sewers. In an attempt to protect their property, people walled the streams and direct them to the estuary… rather ingenious!

Unusually good experience. The museum is very good, even more so considering it was a private initiative, and privately funded. The guided visit is available in English abd Spanish. I took it in Spanish, our guide was Victoria, and she was both thorough and entertaining, she made the vist both informative and fun. As I said, very good experience and definitely worth a visit.

I had the best touring experience in a museum at El Zanjón. I had the English tour at 4pm on a Sunday and as my luck would have it, I was the only one present for that slot. So it became a private tour. My tour guide was Victoria and she was PERFECT. Her presentation, delivery, and guide through history enabled me go back in time and create a visual of how things were. She touched on historical components of the city to synthesize a richer experience for me. I was excited about history and the inner workings of the tunnel. 10/10 all around. The tunnels are amazing and the archeological genius of the museum is present. Nicely done Mr George. When visiting Buenos Aires, you have to visit El Zanjón

Really great museum. We did the guided tour in English. The owner put so much money and effort into making this a beautiful museum. Highly recommend.
