President Juan Perón had the central fountain replaced in 1951 by an amphitheatre with a capacity for 20,000 spectators, a structure lost to arson in 1959.
Mayor Osvaldo Cacciatore had a shallow lake built over 2000 m2 (21,000 ft²) of the central section of the park during the late 1970s, later populated with ducks, swans and other waterfowl.
[1] Parque Centenario increasingly suffered from neglect during the 1980s, a trend underscored by the 1989 theft of the iconic bronze female nude in sculptor Luis Perlotti's Fountain of the Irupé Flower.
Mayor Aníbal Ibarra initiated an ambitious restoration project for the park in 2005, resulting in the reconstruction of the amphitheatre, the refurbishment of the swan lake and the creation of a number of new facilities.
[2] Mayor Mauricio Macri's decision to install a perimeter fence around the park in 2013, however, resulted in a violent protest by opponents of the plan.
