Explore San Telmo on foot
San Telmo’s cobblestone streets, old houses, antique shops and cafés are a short walk from Plaza de Mayo. The neighborhood grew around working-class and immigrant life; today its streets mix long-standing businesses with artists, small shops and visitors. It is worth exploring even when there is no fair.
The Sunday fair and the indoor market are different outings
On Sundays, the Plaza Dorrego antiques fair and stalls along nearby streets make San Telmo especially lively. The City also lists its Sunday Patio de Tango at Plaza Dorrego, although outdoor activity can vary with the weather and the day. If you want time to search individual stalls, make this an independent Sunday outing.
The Mercado de San Telmo is a separate covered market at Defensa and Carlos Calvo. Its iron-and-glass structure dates from the late nineteenth century, and today you can browse food counters and antiques inside. It is open beyond the Sunday fair; check the market’s current information before making a special trip. For a comparison with Palermo’s art fairs and Colegiales’ flea market, see our Buenos Aires markets guide.
Two more stops on a San Telmo walk
At San Lorenzo 380, Casa Mínima is famous for its remarkably narrow façade. The City notes that the tale of an emancipated slave living there is a local legend, not a confirmed account of that particular house. On Defensa 1179, Pasaje Defensa occupies an 1880s house with patios and galleries. These are small, easy additions to a walk rather than reasons to rush across town.
Our Full Day Essentials Tour includes San Telmo and the covered market as part of a route through the city center and Recoleta; on Sundays, that route begins in San Telmo. It is designed for a guided overview, not a long stall-by-stall shopping session. If you want to combine San Telmo with La Boca or follow your own interests at a different pace, explore our private La Boca and San Telmo walking tour.
