Rúpac, Pre-Inca archaeological site in Huaral Province, Peru.

Rúpac is an archaeological site of the Atavillos culture in the Huaral Province, Lima Region, near the villages of San Salvador de Pampas and La Florida. Its stone buildings date to around 1200 AD and stand at 3,580 meters above sea level. The site was declared a National Cultural Heritage in 1999.

Rúpac was built around 1200 AD by the Atavillos culture, and its structures were raised in stone. In 1999 it was declared Cultural Heritage of the Nation by National Directoral Resolution No. 283/INC.

The kullpis and chullpas served as spaces for ancestor worship and burial ceremonies. Food preparation and textile production took place within these structures to support the rituals performed there.

From San Salvador de Pampas, the walk to Rúpac takes about three hours on a moderate ascent to 3,580 metres above sea level. Muleteers in the village rent donkeys to carry camping gear and backpacks, since no road reaches the site. Bring provisions and cold-weather clothing, as mountain weather can change quickly.

The stone structures rise up to 10 meters high and demonstrate advanced building techniques developed by the Los Atavillos for high-altitude settlement. These construction methods enabled stable buildings on challenging mountain terrain without modern tools.
