Dolmens in a Land of Caves: The Azurrague Pre-Historic Monument (Ourém—Central Portugal)

The article presents the preliminary data from the excavation of the Azurrague 1 Dolmen (Ourém), carried out within the MEDICE II project, highlighting the importance of its location in a karstic landscape marked by a strong tradition of funerary cults in natural cavities. The dolmen structure features a heptagonal chamber and a short passage, with ritual deposits that include macrolithic tools, polished axes, ceramics, and human remains dated between the beginning of the Late Neolithic and the Middle Chalcolithic. The data indicates practices of secondary burial, continuity of regional lithic traditions, and a symbolic integration between exogenous architectural forms and endogenous ritual content established in caves. The proximity to caves with contemporary chronologies, such as Lapa da Furada, reinforces the coexistence of differentiated yet interconnected ritual spaces. Analogies with the Rego da Murta Megalithic Complex, caves and other sites in the Alto Nabão region support the hypothesis of a hybrid, long-lasting cultural system in which megalithic monumentalization is associated with ancestral symbolic practices.
