San Telmo is one of the city's oldest and most emblematic neighbourhoods. It still maintains much of its original architecture, with historic mansions, cobbled streets and patios with fountains. You can explore several converted mansions such as the Pasaje Defensa, once the private home of the Ezeiza family, browse for unique items at the many antique shops, catch a tango show, or drink a coffee at a traditional neighbourhood bar.
The neighbourhood has gained a bohemian air thanks to the many artists and musicians in the area, and has a growing gastronomy scene with new restaurants and craft beer houses.
At the heat of San Telmo is the Plaza Dorrego, an old square surrounded by bars. The city's biggest antiques fair takes place here on Sundays, along with the hugely popular market on Defensa street, where you can find everything from antiques to contemporary craft items.
