Chuño negro
Chuño negro is a source-documented Andean potato-preservation practice. This entry records producer tradition; it is not a validated household process for making potentially toxic bitter potatoes safe.

Qollqa (Inca state storehouse)

Qollqas (also called colcas) were fixed Inca state storehouses built in Andean networks. Their forms, locations and stored goods varied by site; Xauxa archaeology documents a large regional system.
A storehouse in an imperial network
Qollqa (also written qullqa or colca) names an Inca storehouse. These were fixed buildings used within a larger system that gathered food, textiles, tools and other supplies and moved them to places where people and state projects needed them. Smithsonian accounts describe colcas as state facilities tied to collection and redistribution across the empire. Their storage role was architectural and administrative as well as culinary.
This record covers the built storehouse type, not a recipe or a single named building. Many sites have their own chronology, materials and local evidence. Archaeologists use the name for a family of structures whose shape and contents could vary.
Evidence from Xauxa
In the central Peruvian highlands, the Xauxa region preserves unusually extensive evidence for state storage. D'Altroy and Hastorf report more than 2,000 storehouses across 52 architectural complexes. Their research describes goods produced by Huanca communities and notes that local people also took part in managing storage. The network was organized across a province rather than concentrated in one warehouse.
Test excavations in six Xauxa storehouses recovered maize, quinoa, potatoes and lupin, alongside fragments of Inca storage vessels. That list is evidence from excavated contexts, not a claim that every room held all four crops. A later account of Hatun Xauxa describes groups on the slopes west of the site, with circular and rectangular structures following the shape of the terrain.
Forms and storage conditions
Museum and archaeological sources describe both circular and rectangular qollqas, usually as compact one-room buildings arranged in clusters or rows. The Smithsonian's overview describes stone construction and thatched roofs. These are documented features of the type; surviving ruins may be roofless, and the remains at a particular site need their own reading.
At Hatun Xauxa, a published account reports 1,069 structures in five groups, with 562 circular and 507 rectangular rooms generally arranged in rows along the slopes. Other Inca sites differ. Research on Huánuco Pampa links shape and placement to particular storage needs, but those site-specific patterns should not be used as a universal blueprint. Museum sources describe location and airflow as aids to keeping goods cool and dry without establishing a single climate-control system for every qollqa.
Stored goods and continuity
Excavated crops are only part of the picture. Museum sources also document clothing, tools and weapons among stored supplies, while the Xauxa research recovered storage-vessel fragments. An exhibit shows dried potatoes such as chuño stored in ceramic containers inside a colca, supporting the related entries for chuño negro and tunta. Those links describe documented storage uses; they do not imply that every qollqa was a potato store.
The photograph linked here shows surviving storehouse ruins above Ollantaytambo in Cusco. It provides a visual example of hillside placement and masonry, while the main archaeological discussion on this page concerns Xauxa in Junín. Both sites are Andean examples; neither image nor account stands for all qollqas.
Site
SettingFixed storehouses arranged in clusters or rows at Inca centers and other strategic places across the Andes.
GroundThe linked image shows hillside ruins above Ollantaytambo; published evidence from Hatun Xauxa describes storehouses arranged along slopes. Ground and siting varied by site.
ClimateSmithsonian sources describe location and design as supporting cool, dry storage and airflow; the available evidence does not justify assigning the same climate system to every building.
NotesA qollqa is site architecture and part of a broader state storage network. Circular and rectangular forms are both documented.
A build is made where it stands: moving it means building it again.
How it is built
Materials
- Stone masonry — The Smithsonian's overview describes qollqas as one-room stone storehouses; the linked Ollantaytambo photo shows surviving masonry. Building materials and masonry detail could vary by locality.
- Thatched roofing — The Smithsonian's overview documents thatch roofs as part of qollqa construction; the surviving Ollantaytambo reference photo is roofless and does not establish a particular roof at that site.
- Stored food and goods — Archaeological and museum sources document crops and other supplies in qollqas. Container use and contents depend on site and commodity.
- Qollqas were built as fixed storehouses within larger Inca administrative and transport networks; the documented Xauxa region contained complexes distributed across the landscape.
- Archaeological accounts describe circular and rectangular one-room forms, often grouped in rows. The form and position of a storehouse should be read from its own site evidence.
- Excavations and museum accounts identify crops and other goods stored in qollqas. At Xauxa, test excavations recovered maize, quinoa, potatoes, lupin and Inca vessel fragments.
- This sequence describes archaeological function and evidence; it is not a construction plan or a claim that every qollqa stored the same crops.
