Ruins of Quilmes, the Sacred City of the Calchaquí Valley
The Ruins of Quilmes are the remains of the largest pre-Columbian settlement in Argentina, in the Calchaquí Valley of Tucumán Province, at the foot of Alto del Rey hill. The Quilme people lived here, and today visitors walk through a partly reconstructed stone city: one of the most fascinating hidden gems of north-west Argentina.
Its people resisted the Spaniards for decades, and in 1667 they were forced to walk more than a thousand kilometres to the River Plate. The Buenos Aires city of Quilmes, named after them, grew from that exile.
The history of the Ruins of Quilmes
The Quilmes lived in the Calchaquí Valley from about the 10th century. They had a very high population density, which allowed them to share out tasks better and make more of the ecosystem; specialists today regard the towns of the valley as the first pre-Hispanic cities of Argentina. Their houses had double stone walls filled with earth and pebbles, and on the hillsides they built cultivation terraces for maize, beans, potatoes, peanuts, squash and chilli peppers, served by a hydraulic system of dams and channels.
The settlement was divided into a residential sector on the alluvial cone and a fortress on the slope of the hill, all surrounded by a wall. The houses were single-room, rectangular buildings linked by patios or streets, while the storehouses were circular. The Quilmes fought bitter conflicts with their Calchaquí neighbours, with whom they finally allied against the Spaniards. First contact with Europeans came in 1562, and several conflicts followed.
In 1667, during the third Calchaquí war, about 400 Spaniards besieged more than 6,000 indigenous people, first cutting off access to their fields and then poisoning their water supply. The Quilmes had bows, arrows, slings and spears; the Spaniards had armour and firearms. After about a month they surrendered, with their cacique Martín Iquín as spokesman. They were forced to walk more than a thousand kilometres to the River Plate; of more than 2,600 survivors who set out, only a little over 400 arrived. The Buenos Aires site is called Quilmes after the mission of Santa María de Quilmes.
The ruins became known in the late 19th century. Samuel Lafone Quevedo found them in 1888 and wrote a series of letters to the newspaper La Nación; Ten Kate visited in 1893, and in 1897 Juan Bautista Ambrosetti made the first detailed study: he drew a map, found a cemetery and linked the Quilmes with the people of Amaicha for the first time. Carlos Bruch followed in 1911, then Schreiter in 1919, who described child burials in funerary urns, and Adán Quiroga in 1929. The site then had no more visitors until 1978.
In 1975 the site was declared a Historic Monument, and in 1978 a restoration project in four stages was approved: clearing the ground, anastylosis of the most significant areas, a site museum and archaeological research. It opened to the public around 1980, although its criteria were later criticised as more tourist-minded than archaeological. In 1992 a ten-year concession was granted, during which a hotel was built. Between 2007 and 2008 the Quilmes Indigenous Community regained control of the place, with a ceremony to the Pachamama on 9 January 2008. Today it is visited with guides and has an interpretation centre.
