Since its inauguration in 1937, 9 de Julio Avenue has undergone multiple changes. It has been lengthened, widened, and lost parking areas. But nowadays, there's a project to restore it to its original glory. It is the widest avenue in the world at approximately 130 meters wide. The Obelisk is, without a doubt, the finest architectural feature of the city. It stands in the center of the interesection of 9 de Julio Avenue and Corrientes and is 67 meters high. It is a memorial of four historical facts related to the city, each of which is recorded on one of its four faces.
