In the municipality of Campo Grande, there is also the urban nucleus of Primero de Mayo, and another important place is Kilometer 17.

Campo Grande was named because it was a field, which was unusual in a closed tropical forest area like the center of Misiones before it was colonized.

In its vicinity, some Brazilian fugitives who lived from hunting and fishing and a Guarani tribe sporadically inhabited.

Then, an old logging road continued to the center of the province, which the jungle had already covered because nobody had used that "picada" for a long time.

Carlos decided to explore that area, ventured into it, opened a path, and came out into a large field, what would later be called "Campo Grande."

They had to widen the path in parts, create roads, work on descents, and build temporary bridges.

Later, he donated part of his land for the construction of School Number 209, the Church, and the Cemetery of Paraje el Tigre, and helped to process the installation of the first Civil Registry of Campo Grande.
