Headquarters of the colonial administration, it occupies the same place since 1580 and is an emblem of living history.
If you like history, you can't miss this building. The Cabildo of Buenos Aires occupies the same place since 1580, but underwent successive building modifications. The first references to this emblematic construction come from the beginning of the 17th century and in 1608 it had adobe walls and a thatched roof. Inside, there was a room for meetings and another reserved to be used as a jail. In 1610, two hundred years before the First Meeting, the roof was covered with tiles. Later, in the middle of the century, they built a balcony and towers of wood and mud.
In 1725 the Cabildo was in very poor condition and was demolished. Subsequently, a new one began to be built based on a project by the Italian architect Andrés Blanqui. Thus, it began to take its form as we know it today. The first floor was completed in 1748 and, in 1773, the tower appeared - a little higher than the current one - whose dome was covered with a tin roof. Yes, canned! That was the patriots' Cabildo of 1810 and it was its period of greatest splendor.
Eleven years after the Argentine May Revolution, the Cabildo ceased to be an institution and began to function as an administrative building.
In 1894, three arches were removed from the north wing to make way for Avenida de Mayo, and in 1931 three more were demolished from the south wing to make way for Avenida Julio A. Roca.
Since 1938, the Cabildo houses the National Commission of Museums and Historic Monuments and Places, and the National Historical Museum of the Cabildo of Buenos Aires and the May Revolution.
Around 1940, the architect Mario Buschiazzo carried out the last major renovation of the building, which partially rescued Blanqui's original design.
