Isidro Casanova: A History of Growth and Community
The story of Isidro Casanova is one of transformation, evolving from a rural landscape of livestock farming into a recognized city. Its development was driven by waves of immigration and the strategic expansion of the railway system, which connected the region to the broader economic networks of Argentina.
Early Foundations and Agricultural Roots
Around 1850, the area that now comprises Isidro Casanova was primarily used for cattle ranches and dairy farms. These early agricultural ventures were established by German Argentine immigrants, who laid the groundwork for the region's initial economic activity.
The Impact of the Railway
The arrival of the Buenos Aires Midland Railway (Ferrocarril Midland de Buenos Aires) in 1909 served as a catalyst for rapid growth. The railway extended southwest into the area, leading to the inauguration of the San Sebastián station. This infrastructure was quickly bolstered by the addition of a railyard in 1910.
In 1911, the Carhué station was opened. While the town does not have a formal, documented establishment date, May 15 of that year was later adopted as the official date of its foundation.

Industrialization and Urban Identity
Shortly after the railway's expansion, the settlement saw its first major manufacturing establishment. This facility was founded by Isidro Casanova, an Italian Argentine immigrant. Following his death, the town was renamed in his honor to recognize his contributions to the local economy.
The town also became a cultural hub, specifically as the home of the largest Portuguese community in Argentina. To honor this unique distinction, one of the town's primary streets was named República de Portugal.
The growth of the settlement culminated on August 29, 1974, when the Provincial Legislature officially recognized Isidro Casanova as a city. For those seeking a deeper dive into these events, local historian Alejandro Enrique published a comprehensive two-volume history of the area in 2010.
