Informal tango in Plaza Dorrego Buenos Aires © Judith Duk
Plaza Dorrego lies in San Telmo, the bohemian artists' quarter and the birthplace of tango. The tiny square is surrounded by elegant houses, now mostly converted into antique shops and bars whose tables overflow onto the street. the historical buildings and sights on and around the plaza are looked after by the Comision del Museo de la Ciudad.
On Sundays the plaza is the setting for the ancient flea market, the Feria de San Pedro Telmo. Though you are unlikely to discover any bargains you may find an interesting souvenir or two. The stallholders pack up their wares at 5pm and the square becomes the setting for informal tango dances. This is as popular with the locals as it is with tourists and even the inexperienced may be tempted to try it out. There are numerous museums nearby the Plaza Dorrego worth visiting, including the Museo Histórico Nacional and the Museo de Arte Moderno.
Aside from the museums, flea market and dancers, another of the main attractions of the square is simply the people watching. Visitors to Buenos Aires would be remiss in not setting aside a whole afternoon to sit at an outdoor bar or cafe table and while away the time until the dancers arrive for the evenings festivities.
