Architecturally speaking, Buenos Aires is fascinating, particularly along the Parisian-style Avenida de Mayo and throughout the historic barrios of San Telmo, Recoleta, San Nicolás, and Monserrat, where the grand Spanish and Italianate buildings stand as testament to the city’s proud immigrant past. On rainy days, see some of the city’s museums—MALBA hosts many of the most significant Latin American art exhibits. For the most authentic taste of porteño culture, you’ll have to wait until after dark, when local dancers crowd the floors of traditional milongas (tango clubs) and imaginative musicians and DJs mix and mash provincial Argentine music with cumbia, hip-hop, and house music in the city’s nightclubs.
Buenos Aires hosts major events throughout the year. The biggest draws are the ArteBA art exposition, Feria del Libro book fair, Tango Buenos Aires Festival y Mundial, Casa FOA design festival, and La Exposición Rural, a farm show−like agricultural fair.
