Pottery was especially important in ceremonies and would not be used during every day tasks or by ethnic groups on a regular bases. The north and south "barrios," or quarters, of Wanuku Pampa were used mostly as residential districts. In some cases, the areas are very formally arranged, such as the "cuartel" in the northern "barrio", which to a European, appears just as an army barrack. Many Inca people lived in rectangular houses with trapezoidally-shaped niches in the interior walls. All of these houses are built from "pirqa" masonry, typically bifacial walls with rubble and mud fill. Many of these houses are arranged around a central courtyard. Ethnic groups moved in and out of the land constantly, because of ceremonies and duties, there is no real large group that have called the land home. However, archeological evidence suggests that one important group of permanent residents were the "Aqllakuna". It was at Wanuku Pampa where the first conquerors founded a city in 1539 which due to the coldness of the climate was then transferred to the pleasant and temperate Pillco valley that lies on the Huallaga River. The storage area at Wanuku Pampa includes 497 qullqas (storehouses) and 30 processing and administration buildings. The city may have been an extremely important redistributive center supplying the provincial villages of the area it administered with the products of other regions. "Qollqas" are constructed in rows and made of "pirqa" masonry, just as the residential districts. The groups of storehouses included: 1) a small zone of storehouses which may have held the stores, of the Sun, the state religion; 2) minor groups of single storehouses apparently devoted to special shrines or ceremonial activities; 3) an ill-defined section of buildings which may have held a wide variety of goods in temporary storage for more immediate uses; and 4), the largest group, which was devoted to long-term storage of various food stuffs and other goods in technologically specialized facilities. Storage was very diverse among crops, for example, root crops were placed in the middle of layers of straw, bound into bales with rope and stored in rectangular structures, while maize was stored shelled, in large jars which were put in circular storehouses with stone floors. Highland root crops made up for 50-80% of the space, while maize made up for 5-7%. The influx of supplies at Wanuku Pampa was quite uneven.
