🇦🇷 Argentina · The North (NOA)
The Sacred City of Quilmes, in Tucumán province, is one of the largest pre-Hispanic settlements in Argentina: a stone city that once held several thousand people and that spreads over some hundred hectares at the foot of Alto del Rey hill, in the heart of the Calchaquí Valleys. This is where the Quilmes people lived, a Diaguita-Calchaquí group that mastered terrace farming, ceramics, weaving and metalwork.
What impresses most as you walk it is the scale and the strategic position. On the hillside you can still see the stone enclosures wedged into the mountain and, higher up, the remains of the pucará: the natural fortress from which the Quilmes watched over the valley and held out first against the Incas and then, for more than a century, against the Spanish. Climbing even part of the way rewards you with a huge view over the dry valley dotted with cardón cacti.
Quilmes is not just an archaeological site: it is the ancestral territory of the Comunidad India Quilmes, which after years of conflict took back the running of the place. That gives the visit an extra layer of meaning. There is an Interpretation Center with themed rooms and, on many tours, guides from the community itself who tell the story from their own point of view. It's usually combined with Cafayate, Amaicha del Valle or Santa María on the same trip along RN40.
The Quilmes were a Diaguita-Calchaquí people who resisted the conquest for more than a century in the Calchaquí Wars, until their fall between 1665 and 1667. After the defeat, the Spanish uprooted them and marched them on foot to a reducción near Buenos Aires, which is where the present-day district of Quilmes was born and where the people died out. The full story — including the controversy over the private concession of the site and its recovery by the community — is on our history page.

Origins, formation and what the sources say.
At the foot of Alto del Rey hill, in the southern end of the Tucumán stretch of the Calchaquí Valleys, stands what was one of the largest and most populated indigenous cities in all of present-day Argentina. The so-called Sacred City of Quilmes spreads over some hundred hectares and, at its height, is thought to have housed several thousand inhabitants. Its people, the Quilmes, were a subgroup of the Diaguita-Calchaquí: Cacán-speaking peoples, farmers and potters who had mastered terrace farming, ceramics, weaving and metalwork.
The city was not built there by chance. It was laid out on the hillside, with its stone enclosures wedged into the mountain and, at the summit, a pucará: a natural fortress reinforced with defensive structures that let them watch over the valley and take shelter from any invasion. That strategic siting, together with an ingenious system of farming terraces and channels to make the most of scarce water, explains how so large a population could sustain itself in a dry, high-altitude region. When the Incas arrived, in the 15th century, the Quilmes were absorbed into the Tahuantinsuyo, but they kept much of their identity.
When the Spanish pushed into the Calchaquí Valleys, they met one of the longest and most stubborn indigenous resistances in what is now Argentine territory. The Calchaquí Wars dragged on for close to a century, in several stages. The first great offensive was led by the chief Juan Calchaquí around 1562; later came new uprisings, such as that of Juan Chelemín in the 1630s. Throughout all that time the Quilmes were one of the most combative strongholds of the resistance, dug in behind their pucará.
The third and last great Calchaquí war, in the mid-17th century, was the harshest. After the uprising headed by the Quilmes leader Felipe Calchaquí, the governor of Tucumán, Alonso de Mercado y Villacorta, launched a ferocious campaign that finally broke the resistance. By 1665 the Quilmes had been subdued by Spanish troops, ending more than a hundred years of fighting. The defeat, however, was only the start of an even greater punishment: the uprooting and exile of the entire people.
Defeated, the Quilmes suffered one of the cruelest decisions of the conquest: desnaturalización, that is, the forced uprooting of entire communities far from their land in order to break any remaining focus of rebellion for good. In 1666 the Real Audiencia of Buenos Aires ordered the deportation from the Calchaquí Valleys of some two thousand Quilmes people to a reducción southeast of Buenos Aires, on the banks of the Río de la Plata.
The transfer was a brutal march of more than a thousand kilometers, on foot and in chains, across the puna, the plains and the pampa. Very many died on the road from hunger, cold, exhaustion and disease. The chronicles and the people's own memory agree that only a fraction of those who set out arrived alive. In 1667 a group of Acalián families, also from the valleys, was added to the exile. With the survivors, south of the Riachuelo, was founded the Reducción de la Exaltación de la Santa Cruz de los Indios Kilmes: the first settlement in the area and the origin of the name of today's district and city of Quilmes, in greater Buenos Aires.
Far from their valley, their climate and their way of life, the Quilmes people faded away. The reducción lasted more than a century, but the community dissolved and, in 1812, by then all but extinct, it was declared disbanded. So the brewery and the city that today carry the name Quilmes in Buenos Aires owe their name to a people from the northwest who were torn from their land and wiped out as such. In their home valley, their stone houses stood silent for centuries.
The recent history of the ruins had its conflict too. In 1992, during the governorship of Ramón 'Palito' Ortega, the province of Tucumán granted the concession of the archaeological site to the businessman Héctor Cruz for ten years, in exchange for a modest monthly fee which — according to the records — was never paid in full. Under that concession a hotel and other facilities were built in the middle of sacred territory, something the descendants of the people, the Comunidad India Quilmes, denounced as having been done without their consent and without the proper impact studies.
When the term expired in 2002 the contract was terminated, but the operator went on profiting from the place for several more years. The community's claim kept growing until, on 28 November 2007, the descendants of the Quilmes blocked access to the site in a standing assembly, demanding the return of their Sacred City. On 13 December that year the police evicted the concession holder and, on 9 January 2008, the community carried out the 'spiritual takeover' of the place with a ceremony to the Pachamama, reopening the site the following day under its own administration. Since then, after a long court process, management has been in the community's hands (at various points shared with the provincial government), and tours are usually guided by its own members. The story told at the site stopped being purely archaeological and became, above all, the living voice of a people claiming its ancestral territory.
Today the Sacred City of Quilmes is at once a first-rank archaeological site and a living territory. Visitors walk the stone enclosures, climb towards the pucará and go through the Interpretation Center opened in 2018, with its themed rooms, its small cinema and its original ceramic pieces. But above all they hear the story from the mouths of guides from the community itself, who link the Diaguita-Calchaquí past with the resistance, the exile and the long road back.
The Comunidad India Quilmes, settled in nearby hamlets such as Colalao del Valle, Amaicha and the area around the site, keeps alive an identity the conquest tried to erase. Visiting Quilmes with that in mind changes the experience: it isn't only about admiring ancient stones, but about recognizing that behind every wall there is a people who were punished, deported and declared extinct, and who nonetheless returned to their land to tell their own story. That combination of monumental landscape, archaeology and living memory is what makes Quilmes one of the most moving places in northwestern Argentina.
