Iron Age ovens and hearths from the hilltop of Quinta de Crestelos, Sabor Valley (NE Portugal): An archaeobotanical approach on typology, functionality and firewood use

The archaeobotanical results, together with the typology of the ovens and hearths, their spatial distribution and ethnographical examples, allowed the discussion of the structure's functionality, the identification of patterns and trends of their use according to different typologies and contexts and the recognition of possible firewood selection and storage practices. This study also provides a preliminary approach to the paleolandscape of the site during the Iron Age of NW Iberia.
