Maray Qalla, Archaeological site in Carlos Fermín Fitzcarrald Province, Peru.

Maray Qalla is an archaeological site in Carlos Fermín Fitzcarrald Province in the Ancash region, situated in mountainous terrain at high elevation. The complex features stone structures integrated into the natural landscape, showing evidence of ancient workshops and processing areas.

Maray Qalla was built as a military and administrative base during the Inca conquest of the eastern highlands of Áncash between 1470 and 1510. After the Inca army was pushed back at the Yanamayo River, it established this fortified center on the puna of what is now Yauya district, from which it directed sieges of Conchucos strongholds. The Inca force of some 20,000 soldiers defeated the confederation after months of siege.

In Quechua, maray means grindstone and qalla carved stone or cobblestone, so the name describes the site's stonework. The complex served as a tambo, a rest and supply stop for Inca troops marching from Cusco, and its corral complex for camelids runs about 100 metres long. Descendants in Chacas still recount the deeds of the rebel leaders Katin and Riway.

This remote location requires preparation and a local guide experienced in mountain navigation to reach safely. Visitors should be prepared for high altitude conditions and bring weather-appropriate gear, as conditions can change quickly.

The complex includes a corral complex for camelids about 100 metres long, beside a tambo and a colca. The Inca road passing the site reaches 7 metres in width there. Maray Qalla sits at 4,260 metres, southeast of Yauya village.
