Dec 20, 2011 was the 10th anniversary of the Argentine economic crisis which led to violent street riots and collapse of the government on Dec 19 and 20, 2001. A massive demonstration was held in the center of Buenos Aires to commemorate this event. It started under the Obelisk, along Av. 9 de Julio and ended up in Plaza de Mayo in front of the Casa Rosada Presidential Palace. These photos give the street-level view of this peaceful, yet powerful, demonstration.
