About the Tour
About the Tour
San Telmo is the oldest neighbourhood in Buenos Aires, and its cobblestone streets hold enough history to fill several lifetimes. On this walking tour, you'll trace how sailors, slaves, immigrants, and tango singers turned a muddy colonial outpost into the soul of the city. You'll also discover how a yellow fever epidemic, two British invasions, and millions of Italian immigrants each left their mark on this single neighbourhood.
The tour starts at Basílica de San Francisco, where a time capsule is hidden inside a stone statue on the facade. From there, you'll walk south along Defensa Street, passing the oldest pharmacy in Buenos Aires and the spot where residents repelled two British invasions from rooftops using stones and boiling water. You'll also hear how that resistance helped spark Argentina's independence movement, and why the street you're walking is named after those events.
Further along, you'll step inside the San Telmo Market, built in 1897 to feed waves of newly arrived immigrants, and visit Casa Ezeiza, a former mansion where 32 families once shared a single building – and where, out of that chaos of languages and longing, tango was born. The tour ends at the Museo Histórico Nacional, housed in the former home of botanist José Gregorio Lezama, whose widow sold the surrounding land to the city on one condition: that it remain a public garden forever.
On this 60-minute tour, you'll have a chance to:
- Visit Buenos Aires' oldest and most beautiful pharmacy and admire its stunning frescoes of Farmacia La Estrella Homeopatía.
- Spot the British cannonball marks still etched into the stone towers of Nuestra Señora del Rosario
- Explore El Zanjón de Granados, where a buried colonial river runs beneath a restored former tenement
- Stand outside Casa Mínima, the narrowest house in Buenos Aires, once associated with freed slaves
- Hear the story of El Viejo Almacén, where the same corner gave Buenos Aires both tango and football
- Visit San Telmo Market and try the delicious choripan, dulce de leche, wine, empanadas and steak
- Discover the tragic legend of forbidden lovers who fled through underground tunnels at Antigua Tasca de Cuchilleros
By the end, you'll understand why porteños say San Telmo isn't just a neighbourhood. It's where Buenos Aires became itself.

I'm Maggie, and I believe every city has stories waiting to be discovered.
For the past four years, I've been guiding travelers through Buenos Aires in English, introducing them to the history, architecture, and unforgettable characters that have shaped this remarkable city. My favorite moments are when visitors tell me they've started seeing Buenos Aires with different eyes.
I deeply love my country, its culture, and its history. Sharing that passion is the reason I started leading walking tours, and it's what inspires every story I tell. I hope that by the end of each tour, you'll not only know Buenos Aires better—you'll understand why so many of us are proud to call it home.
I'm especially drawn to the places where history comes alive: elegant buildings, hidden courtyards, lively markets, and the streets where politics, immigration, tango, and everyday life have intertwined for generations.
With my VoiceMap tours, you can explore at your own pace without missing the stories that bring each location to life. Think of me as your local companion, walking beside you and revealing the details that most visitors never notice.
I hope my tours leave you with more than great photos—I hope they help you experience Buenos Aires the way I do: with curiosity, appreciation, and a genuine connection to its people and its stories.

This is the narrowest house in Buenos Aires. It is only 2.5 metres wide, about the size of a parking space, so if you stretch your arms you can almost touch the full extension of both wall...

Directions to Starting Point
The tour begins at the corner of Defensa and Adolfo Alsina, specifically at Adolfo Alsina 400. On one corner, you'll see a small plaza; across from it, an imposing church; diagonally from the plaza, an old pharmacy; and on the corner diagonal to the church, an old colonial-style white building.
This location is just one block from Plaza de Mayo — so if you arrive from plaza de mayo look for defensa street, head south, meaning in the direction where the street numbers decrease.

Places to stop along the way
If you want to try a real Argentine steak experience, stop by El Desnivel, a comfort food restaurant with excellent grilled meats, located at Defensa 855. And if you're up for the full authentic experience, order a 'parrillada' — a mixed grill that includes a selection of meats along with the delicious chinchulines, chorizo, and blood sausage. If you'd prefer a more upscale steakhouse, La Brigada is a more touristy but excellent alternative, less authentic but still excellent, located at Estados Unidos 465.
If you love beautifully decorated old mansions, there's a lovely and famous bar called Atisbar for a drink in a very special setting — especially nice in the early evening for a drink or a coffee. Peru 1024.
Best time of day
Ideally, do the tour during the day (up to 8pm) so you can go inside several of the stops along the way. At night it's also interesting. If it's a Sunday, Defensa Street will be packed with stalls, live music, and street performers, and there will be a lot of people — it's a lot of fun, but if you're not a fan of crowds, you might prefer to go on a different day
Precautions
The area is safe, but as in any big city, it's best to stay alert to your surroundings. On Sundays, when the street fair is on, San Telmo indoor Market gets very crowded — keep an eye on your phone and wallet. San Telmo's streets are cobblestone and the sidewalks are quite narrow, so watch your step, and it's best to wear comfortable shoes.
