San Luis: The Historic Capital of Argentina's Cuyo Region
Nestled at the foot of the Sierras Grandes, San Luis serves as the capital of the San Luis Province within Argentina's Cuyo region.

History and Evolution
San Luis was first established on August 25, 1594, by Luis Jufré de Loaysa y Meneses. Although the initial settlement was abandoned, it was reestablished in 1632 by Martín García Oñez de Loyola under the name San Luis de Loyola Nueva Medina de Río Seco.
The city underwent significant modernization in the late 19th century. By 1882, the Argentine Great Western Railway arrived, facilitating connections toward Chile. This era saw the beginning of the cathedral's construction and the 1911 completion of the Governor's Executive Building, which features French renaissance architecture.
While the population stood at 7,000 by the end of the 1800s, it grew to 40,000 by 1960. This growth accelerated due to the rise of light industry and an influx of retirees, reaching 153,322 by the 2001 census.
