Avenida de Carlos III begins at the intersection with the Ayestarán and Presidente Menocal or Calle Infanta.

[3] The beautification plan of Havana by the engineer Mariano Carrillo de Albornoz during the third decade of the nineteenth century, contemplated the construction of a comfortable and beautiful walk that would serve for the recreation of the city's residents who were already spreading to more and more of its original city limits and as framed by the original wall that protected them from foreign attacks.

There was also another reason that turned the work into doubly useful, which was the frank communication of this square with the castle, interrupted by that part in the rainy season.
