Tilisarao is a village and municipality in the Chacabuco Department of San Luis Province, central Argentina. It is located in the Valle de Conlara along National Route 148, approximately 33 km from the departmental capital Concarán, 61 km from Villa de Merlo, 136 km from the provincial capital San Luis, and 814 km from Buenos Aires.
Toponymy
The name "Tilisarao" is believed to derive from indigenous languages. According to one interpretation, it comes from words of Kakán or Diaguita origin: tili (abundant or fertile), sar (maize), and ao (region), together meaning "Region of Abundant Maize" or "Land of Wild Maize." Other sources attribute the name to the nearby Sierra de Tilisarao.
History
The settlement originally developed around a railway station called "Estación Renca," inaugurated in 1904 as part of the Ferrocarril Buenos Aires al Pacífico line. The station was built on land donated by Cleófe Domínguez. The area was initially known as "Nueva Renca," but in 1925, at the request of local residents, provincial authorities officially changed the name to Tilisarao.
While the official founding date is recognized as 21 September 1889 by decree of the provincial government, the first railway tracks arrived on 25 November 1904, a date long celebrated as the town's foundation. Beginning around 1908, immigrant families from northern Italy (particularly the Piedmont region) settled in the area, focusing on agriculture. Immigrants from Spain and Syria-Lebanon also arrived, with the latter primarily engaging in commerce. In 1925, the Sociedad Unión Agrícola de Estación Renca was established to protect local farmers' rights.
