The Legislature of the Autonomous City of Buenos Aires (C.A.B.A.) or Legislature Porteña is the legislative branch of the City of Buenos Aires
Its headquarters is located between the streets Hipólito Yrigoyen, Diagonal Julio A. Roca and Peru, which shapes a large triangle whose compact outer volume fits the measures of the plot and it only stands out from other buildings for its clock tower, which crowns the Palace Ayerza, also known as Palace of the Legislature of the City of Buenos Aires.
The architect Hector Ayerza sought to work in a French Academist style Louis XIV for this building which opened its doors in 1931.
The front sports Corinthian style columns and balconies level with the main floor with an epoch balustrade. There are Greek masks over the arches. The old municipal coat of arms made in bronze presides over an ample set of windows. The main gate on Julio A. Roca Av. and Peru St. presents each of its wooden sections carved and with a large central knocker of forged bronze with the shape of a lion’s head.
Surrounding the building, on the last floor, there are 26 sculptures made the epoch’s artists and recreate French classical models linked to the government of a city.
