Sayhuite Stone (Saywite)

The monolith is a granite block of about 4 m × 2 m × 2.5 m (the upper half of an outcropping rock) located on Concacha hill, Curahuasi district, Abancay province, Apurímac region, at ~3,500 m altitude. The material is granite — the site's other blocks, in andesite, are distinct.

The surface presents more than 200 bas-relief figures: felines (pumas), frogs, reptiles, monkeys, condors, crabs — fauna from the three Andean geographic zones (coast, highlands, jungle) — as well as agricultural terraces, irrigation channels, basins, tunnels, stairs and platforms. Traces of successive modifications to the channels indicate active use over time.

Attribution to the Inca Empire (15th–16th c.) is the majority reading (Hemming, *Monuments of the Incas*, Thames & Hudson, 1982/2010, p. 184). The Apurímac region was historically a territory of the Chanka confederation, defeated by the Inca before their expansion; a Chanka or Wari origin has been suggested but is not supported by any published stratigraphic excavation.

No absolute dating (radiocarbon, OSL) has been published for the monolith itself. Peer-reviewed academic literature specifically devoted to the site is nearly nonexistent — the 15th–16th century date rests on cultural context, not a direct measurement.
