Example of an English tour: Balvanera: tango and the Abasto market
Moving away from the main tourist circuit, the neighbourhood of Balvanera was originally a suburb of Buenos Aires that grew through immigration and gained importance in the city's cultural, commericial and political history. The neighbourhood became particularly associated with tango, gaining a picaresque reputation at one time, and today has monuments to some of the genre's icons. Places of historic interest include Plaza Miserere, where troops gathered to resist the British invasion of 1806, several noteable examples of neo-classical, art nouveau and eclectic architecture, and the historic cafes Los Angelitos and La Perla - a favourite with intellectuals and later one of the birth places of Argentine rock music.
Our guided walking tour visits legendary tango singer Carlos Gardel's house - now a museum dedicated to the singer's memory, and the Abasto - a former Art Deco market now regenerated into a modern shopping centre.
