Cobblestone streets and colonial facades define one of Buenos Aires' oldest districts, where history and tradition remain deeply rooted. Established in the 17th century, the area was once home to aristocratic families before waves of immigrants shaped its multicultural identity. The renowned Feria de San Telmo draws visitors every Sunday, transforming the streets into an open-air market filled with antiques, handicrafts, and street performances. Tango culture thrives in its historic cafés and intimate dance halls, where live music and dancers capture the essence of Argentina’s most famous art form. Traditional parrillas serve authentic asado, while hidden speakeasies and local taverns introduce a different side of nightlife. Discover the hidden history of Buenos Aires beneath the surface at El Zanjón de Granados. This museum reveals a network of old tunnels, sewers, and cisterns, offering a glimpse into the city's earliest days. By day, artists and musicians animate the streets, and by night, candlelit restaurants and hidden speakeasies make San Telmo an enduring symbol of Buenos Aires.
