La Rioja
Explora Nuestras Provincias y sus Riquezas is part of Argentina al Mundo, alongside Argentine Delights, Guía AD-Gourmet and Chefs Argentinos al Mundo.
La Rioja, land of red stone and wind. The canyons of Talampaya hold dinosaur tracks and ancient petroglyphs, and the Famatina watches over the valleys. In Aimogasta the Arauco olive is born, unique in the world, and in Chilecito, Riojan Torrontés perfumes the vineyards. Land of caudillos, of the Tinkunaco and the chaya, and of the Syrian and Lebanese immigration that leaves its flavor and its surnames. La Rioja is not rushed: it is contemplated. La Rioja is silence that speaks.

Natural wealth
The territory that defines it
La Rioja is red stone, wind and silence. In Talampaya National Park, sandstone walls carved over millions of years hold Triassic fossils and petroglyphs of ancient inhabitants; together with Ischigualasto, in San Juan, it forms a UNESCO World Heritage Site. High in the Andes, the Laguna Brava Reserve, a Ramsar site, shelters flamingos and vicuñas at more than 4,000 meters. The Famatina massif dominates the valleys of Chilecito and Famatina, and to the east open the Sierra de Velasco, the Cuesta de Miranda and the plain of Los Llanos.

Inaugurated in 1904 and completed in 1905, it carried gold, silver and copper ore down from the La Mejicana mine, in the Famatina, to the Chilecito station: a 34.3-kilometer route, nine stations and a drop of 3,345 meters. Built by the German firm Bleichert, it was one of the great engineering works of its time and operated until 1927. It is a National Historic Monument, and its Station 1 is now a museum.

Human wealth
The living figures
La Rioja is faith and celebration. Every 31 December, the Tinkunaco brings together Saint Nicholas of Bari and the Niño Alcalde in the square in a rite of encounter born of Diaguita history. In February, the Chaya, its carnival, celebrates the harvest with basil, flour and vidalas. The Riojan table is one of olives, walnuts, empanadas, kid goat and homemade sweets, accompanied by Riojan Torrontés, the emblematic grape of its valleys.
- Before the conquest · Diaguita peoples inhabit the valleys and leave their petroglyphs in Talampaya; the Inca Empire incorporates the territory into the Qhapaq Ñan
- 1591 · Juan Ramírez de Velasco founds the city of Todos los Santos de la Nueva Rioja
- 1593 · according to tradition, Saint Francis Solano mediates peace between the Diaguita and the Spanish: the origin of the Tinkunaco, which the city celebrates at the end of every year
- 19th century · the caudillos Juan Facundo Quiroga and Ángel Vicente "Chacho" Peñaloza, born in Los Llanos, shape national history
