Located in downtown, between Rivadavia Ave. and Hipólito Yrigoyen Ave. and Bolivar St. and Balcarce St. This is the city’s most historical place. Argentina’s most important events happened here: May Revolution of 1810, the Constitution of 1860, the massive Peronist concentration of 1945, the events of December 2001. Every Thursday the Mothers of May Square gather here to claim for their missing children. Across the street from the Square lies the Casa Rosada (seat of the National Government), the City Hall and the House of Culture, the Cabildo and the Cathedral. Warning: watch out with the pigeons of the Square. They can leave you a “present”. You can buy corn or bread to feed them.
