Plaza Libertad Plaza Libertad is the location of the ''Monumento de los Héroes'' (Monument to the Heroes), a commemoration of the centenary of the "First Cry of Independence" in 1811. The monument, designed by Francisco Durini Cáseres, and installed in 1911, is crowned by an "angel of freedom" at its pinnacle holding a laurel wreath in both hands. As a consequence of increased commercial activity, the area around the plaza was enhanced with the construction of two ornate buildings, the ''Portal la Dalia'' in 1915–1916 and the ''Portal de Occidente'' in 1917.
