Quilmes Ruins

The Ciudad Sagrada de Quilmes covers a hillside in the Calchaquí Valleys with terraces, walls and the foundations of some hundreds of stone dwellings, the remains of a settlement that at its height may have held several thousand people, making it the largest pre-Columbian urban site in what is now Argentina. Built by the Quilmes people from around the ninth century, it climbs the slope in defensive tiers, with fortress structures at the top commanding the valley in both directions. The site is deeply significant to the Quilmes community, who administer it today, and interpretation is given from their perspective. Climbing the terraces takes effort in the dry heat but gives a clear sense of the settlement's scale and position.

What's there

• The terraced hillside - hundreds of stone house foundations climbing the slope.
• The upper fortresses - defensive structures commanding the valley.
• The cactus slopes - cardon cacti standing among the walls.
• The community interpretation - the site told from the Quilmes perspective.

When to go

April to November for dry, cooler air; summer midday heat on the exposed slope is severe. Early morning and late afternoon are best for both climbing and light. Allow time for the walk up, which is steep and loose in places.

Good to know

What remains is low walls and foundations, so the site rewards imagination and a guide more than a quick look. There is almost no shade and the climb is tiring at altitude. Facilities are limited, and opening arrangements can change with community decisions.
