Probably the oldest building in all of Buenos Aires ! The "Cabildo" was the center of power in all Spanish colonies and was always one of the first building to be built! It has evolved all over the years but is now back to looking more or less what it looks like at the time of the first European settlers. Today it's a museum about the early history of #argentina and the Independence process. The entrance is free! #travelbuenosaires #argentinianhistory
