New Advances in Iberian Medieval Agriculture: Plant Remains from the Islamic Site of Castillo de Valtierra (Navarre, Northern Spain)

Abstract

There has been a notable lack of archaeological research into the medieval period in Iberia, particularly in comparison to earlier periods. Consequently, the majority of our current understanding of agricultural practices and plant food sources in this region is derived from textual sources. However, there has been a notable increase in interest in archaeobotanical studies in medieval contexts over the past decade. In this context, this paper presents the results of a study of plant remains from Castillo de Valtierra (Navarre), with the objective of providing insights into agricultural practices and dietary habits during the Islamic period. In this area (the Ebro Valley), the Islamic period is divided as follows: Emiral period 756–929 AD, Caliphal period 929–ca.1012 AD, Taifal period ca.1012–1119 AD. This period was followed by the Christian period from 1119 AD onwards. Samples were collected from a variety of contexts in a systematic manner. A total of 2574 remains were recovered, and 57 taxa were identified. The findings of this study demonstrate that the community that inhabited Valtierra was primarily engaged in agricultural activities and had access to a diverse range of crops sourced from various productive areas, including cereal fields, home gardens, and forests.
