In the center of Plaza de Mayo is a 61.5 foot, white monument named Pirámide de Mayo. The first May Pyramid was constructed in 1811 to celebrate the one-year anniversary of the May Revolution (Revolución de Mayo). During a major renovation in 1856, sculptor Joseph Dubourdieu created the nearly 12 foot image of Liberty, the Roman goddess Libertas. Beneath it is a relief of the Sun of May. This signifies Argentina’s rise as a glorious new nation.
