With the Casa Rosada to the west and the city hall to the east, the Plaza de Mayo is undoubtedly the political nexus of Argentina. From famous speeches to white-hooded mothers united in a call for justice, the plaza has long been the focal point of the country's most compelling dramas.
The US might have the White House, but Argentina has the Pink House. The Casa Rosada at the eastern extreme of the Plaza de Mayo is the seat of the country's government, where the President and her staff work. On weekends, you can tour the building for free.
