The existence of a fire event at the Iron Age hillfort of Nabás, which is located on the southern bank of the Ría de Vigo (Galicia, NW of the Iberian Peninsula), favoured an extraordinary preservation of carbonised plant remains and offered an unusual opportunity to focus our research on the study of the final episode of a house life-cycle. The archaeobotanical approach focused on perishable materials combining charcoal, with carpology and pollen analysis, in tandem with a taphonomic assessment. The charcoal assemblage includes charcoal without signs of working, and wooden manufactures although the former group was probably related to the roof and timber of the round-house. This interpretation is based on the size and concentration of charcoal fragments, as well as the short taxonomic list (deciduous and evergreen Quercus sp., Fabaceae, Corylus avellana, Rosaceae/Maloideae, Salix/Populus, Alnus sp., Frangula alnus, Betula sp., Phragmites/Arundo and Ulmus sp.), and the recurrence of biological alterations such as xylophages’ galleries and hyphae. Aggregated grains and chaff of foxtail millet (Setaria italica) were found in several samples suggesting their storage, probably inside an organic container. Finally, pollen analysis offered clues about the uses of plants such as Ericaceae during the occupation phase of the round-house.

大火过后：Nabás（西北伊比利亚）铁器时代遗址的房屋生命周期结束

位于维加河南岸（伊比利亚半岛西北部加利西亚）的纳巴斯铁器时代的山堡发生火灾，这有利于对碳化植物遗体进行非凡的保存，并为人们提供了难得的机会将我们的研究重点放在房屋生命周期最后阶段的研究上。考古植物学方法侧重于将易腐烂的材料与木炭相结合，并结合果肉学和花粉分析，并结合一项完整的评估。木炭组合包括没有工作迹象的木炭和木制产品，尽管前一组可能与圆形房屋的屋顶和木材有关。这种解释基于木炭碎片的大小和浓度，以及简短的分类列表（落叶和常绿栎类）。属，豆科，欧榛，蔷薇科/苹果亚科，柳属/杨属，赤杨属，Frangula桤木，桦木属，芦苇/芦和榆属），和生物变化，如xylophages'画廊和菌丝的复发。在几个样品中发现了谷子（Setaria italica）的聚集谷物和谷壳，表明它们可能存储在有机容器内。最后，花粉分析提供了有关在圆形鸡舍占领阶段使用植物如绢毛科的线索。
