Storage pits are undergroundcists that were used historically to protect the seeds for the following year's crops, and to stop surplus food from being eaten byinsects androdents. These underground pits were sometimes lined and covered, for example with slabs ofstone andbark and tightly sealed withadobe.[1]
Sannai-Maruyama Site inAomori,Aomori Prefecture,Japan, contains storage pits that were used whenhunter-gatherers developed from a nomadic lifestyle to settled villages about 3900 BC to 2900 BC. Large storage pits were built underground to conceal their presence, a preferred method used by mobile populations in many parts of the world.[2][3][4]
Worlebury Camp storage pits are 93 storage pits found at theIron Agehill fort that stood north of the town ofWeston-super-Mare inSomerset, England. The pits were cut intobedrock for "keeps", one is a ditch for protection[5]), and 74 are outside the "keep" but still enclosed within the exterior walls.[6] The inhabitants used them to store grain, as is evidenced by thekernels ofbarley andwheat and the shards of pots that were found in the pits. Also found were remains of burned woven baskets and, dated to the 2nd or 1st century BC, sling stones andspindle whorls.[6][7] and close to the village ofWorle.[8] Remains of human skeletons were found in 18 of the pits,[9] 10 of which show evidence of a violent death.[10][11]
Māori storage pit sites remain clearly visible in many place inNew Zealand.[12][13] Pits were dug into soft rock faces as well as into earth, especially inMaori Pa (hillforts). Maori storage pits can be confused with fighting pits and also pits which were excavated to extract drainage material, especially on old river terraces where pumice had been deposited. The pumice was mixed with heavier soil to promote drainage for growingkumara (sweet potato), the principal vegetable crop of the Maori after about 1500. TheMaori name for a storage pit isrua. An excavation found such storage pits on the sloping banks of theWaikato River below theWaikato Museum in early 2012.[citation needed]
