The towns of Quilmes (left) and Avellaneda (right) are split by Calle Caviglia. The informal section in Quilmes, called Villa Azul, was the site of the country's first total quarantine, enforced by the military to mitigate a fast-spreading outbreak in May 2020.

Today that street has become a symbol of injustice, which shows the inequality we live in and the need to advance the political decision to urbanize the neighborhood."
