"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."

A MUST-SEE place !!! What a story to tell here! Visited this place today ( Nov 30, 2025) with my Viking Cruise co-travelers. Mr. Jorge Eckstein ( photographed with me) purchased this building in 1980 to open a restaurant. Soon after he found out treasure- history of the past beneath the floor. It took him long 25 years to complete the excavation and to open as an archaeological place! More to that all the paintings on the walls are drawn by his wife. Our guide didn’t tell us earlier and so I got a chance to take 3 photos near the exit. It’s amazing to see such place in the middle of city! A whole underground tunnel with cistern etc. We had lovely Empanada with meat and also with vegetables ( mostly Spinach ) for vegetarian. Those were delicious! It was a lovely short excursion!!

We got to do a tour which offers a behind the curtain look at life in Buenos Aires back in the 1800s. Our tour guide was very knowledgeable and engaging. She made an effort to encourage conversation and made space for questions. The person who bought, restored and opened this house to the public, very clearly loves the city of Buenos Aires. You can tell that love was put into the restoration and the design of the exhibition. This needs to be on a "Must Do" list when visiting Buenos Aires. Make sure you visit the bathrooms!!!

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.

Incredible place. I went with no expectations, just because I saw it in a YouTube video and I ended up amazed by the architecture and most of all, the history behind those walls. Felicidades Don Jorge! Gran trabajo!

Beautifully restored and upgraded space. Cudos to the owner for creating this space. The tunnels lighting is intricate and delicate. An architect or an engineer would have fun here

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.

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!
