Between the turn of the twentieth century and World War II several waves of European immigrants arrived in Buenos Aires in search of a better future.
Many of them found lodging in the big old houses of the San Telmo, La Boca, and Montserrat neighborhoods. Singles, couples, and even complete families lived in poor rooms giving on to a common inner patio. These collective lodgings, the conventillos, became a milestone in the history of the city. The energy derived from the tenant's swarming dreams, gossip, and fights gave birth to tango.
