Arwaturo, Archaeological site in Chupaca Province, Peru.

Arwaturo is an archaeological site containing ruins of residential buildings and storage structures spread across several kilometers. The remains show different levels with circular formations and reinforced walls.

The Huanca built Arwaturo during the Late Intermediate Period (1200–1450 CE), and the Inca occupied it after their conquest in the Late Horizon. Its 27 structures stand on a plateau above the Ñahuimpuquio lagoon at 3,460 m, 5 km from Chupaca and 16 km from Huancayo.

The people who lived here built round houses and created storage buildings for keeping crops like potatoes and quinoa through the seasons. This way of building shows how well they managed life at high altitude.

Arwaturo lies at 3,460 m above sea level, 5 km from Chupaca and 16 km from Huancayo, west of the Ñahuimpuquio lagoon. The walkable area covers more than 3 km of open ground, so allow time and wear sturdy shoes. Bring water, food and warm clothing for the cold, thin air.

The name Arhuaturo combines two Quechua words: "arhua" (burnt) and "turo" (bone), giving "burnt bone" or "yellowish bone". The site holds 27 structures in three groups: Arhuaturo with 16, Huinsho with 11, and a religious and guard quarter.
